This document is a report submitted by five students at North Western University in Khulna on the topic of light phenomena. It begins with an introduction to light, defining it as an electromagnetic wave made up of oscillating electric and magnetic fields. It then outlines some key properties of light, including that it travels in straight lines, can be reflected, refracted, undergo diffraction and interference, and has both wave-like and particle-like properties. The report further explains the phenomena of reflection, refraction, diffraction, and constructive and destructive interference. It concludes by thanking the reader.

3. Title: Light Phenomena
Content
1. What is light
2. Properties of light

4. What is light?
 Light is an electromagnetic wave, namely the wave vibration of
which Is electric field and magnetic field.
 Visible light: Is a light wave we can see. It is a mixture of all the
colors of the rainbow.

5. Properties of light
 Light rays travel in straight lines from the light source.
 When it hits an opaque object, some light is absorbed and the rest
reflects off.
 If the object is transparent, light rays pass through it easily
 If the object is translucent some light can pass through but rest of the
light will be reflected.
 Light travel very fast
 Light has a dual nature
 Light carries energy and information

6. Light Properties

7. Reflection
 Diffuse Reflection: Reflected rays go in different direction.
 Regular reflection: Reflected rays go in one direction

8. Refraction
 This Usually happens when the light travels from one medium to the
next medium and follow snel law.

9. Diffraction
 This is defined as the bending of light waves around obstacles in its
path.

10. Interference
 Constructive interference: Crest of one wave crest of another wave
adding to a wave of increase amplitude
 Destructive interference
 Crest of one wave overlaps the trough of another , amplitude effects
are reduced.
