Our eyes have limitations that can impact our vision. Optical illusions occur when the brain cannot accurately interpret what the eyes see. The blind spot is a point on the retina that contains no light receptors and so cannot detect images, meaning we cannot see objects whose images fall on the blind spot. We have limitations in our sight due to optical illusions which confuse the brain and the existence of a blind spot in each eye where no vision is possible.

Limitation of sight and hearing
This document discusses the limitations of human sight and hearing, and devices that can overcome these limitations. It describes how sight is limited by things like optical illusions, blind spots, inability to see distant or tiny objects, and inability to see through opaque materials. Hearing is limited by only detecting a certain range of frequencies, decreasing ability to hear as we age, and inability to hear distant or soft sounds. The document then explains that devices like telescopes, microscopes, and hearing aids can help overcome limitations of sight and hearing by allowing users to see farther, smaller things, and hear better. The objective is to understand our senses and devices that enhance them.

Program intervensi bi tahun enam
This document outlines an English language intervention program for Year 6 students in 2016. It describes 3 programs targeting different groups of students. The advance group focuses on more challenging grammar and vocabulary exercises. The average group works on a variety of activities to improve weak topics and writing simple and compound sentences. The slow-learner group acquires basic vocabulary through fun activities and forming simple correct sentences. The programs aim to improve students' English skills and will take place from February to September 2016.

Sound and hearing
1. Sound is produced by vibrations that transfer kinetic energy to air molecules, which are detected by the eardrum.
2. Sound needs a medium to travel and moves fastest through solids and slowest through gases.
3. When sound hits a surface, it can be reflected or absorbed, with hard, smooth surfaces reflecting more sound.
4. The human range of hearing is typically 20-20,000 Hz, but this range decreases with age and exposure to loud noises. Devices like amplifiers and stethoscopes can help overcome limitations.
Chapter 1 form 2

2) It then focuses on the senses of touch, smell, and taste. It provides details on the skin and its sensitivity levels, the nasal cavity and smell receptors, and the tongue and taste buds.

The world through our sense
The document discusses the various sensory organs in the human body and how they detect stimuli from the environment. It describes the skin as the sensory organ for touch, and explains how receptors in the skin detect different stimuli like temperature, pain, and pressure. It also discusses the nose and how olfactory receptors detect smells, as well as the tongue and how taste buds detect the four basic tastes of salty, sweet, sour, and bitter. The ear is described as the sensory organ for hearing, with explanations of how sound waves travel through the outer, middle, and inner ear to the brain. The eye is also summarized, with descriptions of its different parts and how light is focused onto the retina to produce nerve impulses for vision.
Chapter 2 nutrition
1. A balanced diet containing the seven classes of food is necessary to meet daily nutritional requirements and prevent deficiency diseases.
2. The digestive system breaks down food through physical and chemical digestion in the mouth, stomach, and small intestine to absorb nutrients in the bloodstream.
3. Constipation can be caused by not eating enough fibre or drinking enough water, and can be cured by consuming laxatives, high-fibre foods, and more fluids.
Express Notes Science Form 2
1. The document discusses the classification of organisms and their sensory organs.
2. It describes the five senses in humans and the sensory organs associated with each sense. The pathways from stimulus to response are also explained.
3. Various plant responses like tropism, nastic movements and their stimuli are mentioned.
SENSES
The document discusses the five human senses - touch, smell, taste, hearing, and sight. It describes the sensory organs associated with each sense, how stimuli are detected by sensory receptors, and how nerve signals are transmitted to the brain. For each sense, it provides details on the sensory pathways, common stimuli, and examples of sensory responses. The roles of light and sound in vision and hearing are also examined. In under 3 sentences, the document provides an overview of the human sensory systems and how they detect external stimuli and transmit nerve signals to the brain.

Human eye and retina anatomy
The retina of the human eye contains rods and cones, which are light-sensitive cells. Rods are more numerous in the retina and are sensitive to dim light, while cones are concentrated in the fovea and responsible for color vision and sharp central vision. The retina converts light signals into electrical signals through photopigments in the rods and cones, and transmits these signals through the optic nerve to the visual cortex in the occipital lobe of the brain for processing and interpretation.
Light and sight
The eye accommodates by increasing its lens power to 59.6 diopters.
2. The lens power is 59.6 diopters & the focal
length is:
f = 0.25 m
3. The near point for a normal eye is 0.25 m.
4. Presbyopia occurs when the eye loses its ability
to accommodate for close objects. The near point
increases beyond 0.25 m.
So in summary, the eye changes its focal length to focus on objects at different distances by changing its lens power through accommodation.
The blind spot
The document discusses the blind spot in human vision. It explains that the blind spot occurs because the optic nerve exits the eye, leaving a gap where no photoreceptors are present. It notes that photoreceptors detect light and darkness and send this information to the brain via the retina and optic nerve. The document also provides an experiment to locate one's own blind spot and explains that we do not regularly notice the blind spot because the brain fills in the missing information from the other eye.
The human eye
The human eye consists of eight main parts - the sclera, cornea, iris, pupil, choroid, crystalline lens, retina, and optic nerve. Light enters through the cornea and is focused by the lens onto the retina. The retina contains light-sensitive rod and cone cells that generate signals sent by the optic nerve to the brain, where they are interpreted as vision. Common vision defects include near-sightedness and far-sightedness, which can be corrected using concave or convex lenses, respectively.
Blind spot in the eye
All humans have blind spots in their eyes where the optical nerve connects the retina to the brain, resulting in an area without light detecting cells that cannot see. While a small object can disappear from view in the blind spot, people do not normally notice it in everyday life because the eyes are constantly moving to take in varied views, and the brain uses information from both eyes to compensate for any blind areas in individual eyes.
Multimedia Object - Image
The document discusses different types of multimedia compression formats including GIF, JPEG, MPEG, and WAV. It explains the differences between lossy compression formats like JPEG and MPEG which can lose some data quality versus lossless formats like GIF and ZIP. The document also covers color spaces, digital image representation, and the compression algorithms used in common formats such as GIF using LZW compression and JPEG using discrete cosine transform quantization.
Science Form 2:Chapter 1
The document discusses the five senses and their corresponding sensory organs. It describes how each sensory organ detects a specific type of stimulus: the skin detects touch, pressure, heat and cold; the nose detects smells; the tongue detects tastes; the ears detect sounds; and the eyes detect light. It then presents an experiment where different stimuli are presented and the observations of the resulting sensations are recorded to demonstrate the relationship between each sense, sensory organ, and detected stimulus.

Limitation of sight
- 1. Limitation of sight Optical Illusion& Blind spot& Blind Spot
- 2. Optical Illusion Sometimes what we see may not appear to be the real thing. This is because the brain cannot interpret accurately what is actually seen by the eye. This limitation of the sense of sight is known as optical illusion (confusion of the brain)
- 10. Blind spot The blind spot is a point on the retina of the eye that cannot detect any images. The blind spot does not have any receptors sensitive to light and is found at the beginning of the optic nerve. We cannot see an object if its image is formed on the blind spot.
