LAW OF REFLECTION

1. LAW OF
REFLECTION

2. LAW OF REFLECTION
The angle of incidence is
equal to the angle of
reflection.
𝜽𝒊 = 𝜽 𝒓

3. LAW OF REFLECTION
The normal line,
incident ray, and the
reflected ray lie on the
same plane.

6. MIRROR LEFT-
RIGHT REVERSAL

7. MIRROR LEFT-RIGHT
REVERSAL
The left side of the object
appears as the right side of the
image and the right side
appears as the left. This effect is
known as the mirror left-right
reversal.

9. MULTIPLE
IMAGES

10. MULTIPLE IMAGES
Multiple images are formed
by the reflection that
happens when arranging at
least two mirrors.

11. MULTIPLE IMAGES
The number of images, N,
can be determined using the
formula
𝑁 =
360
𝑎𝑛𝑔𝑙𝑒 𝑏𝑒𝑡𝑤𝑒𝑒𝑛 𝑡ℎ𝑒 𝑚𝑖𝑟𝑟𝑜𝑟
− 1

13. SPECULAR/REGULAR
This is a reflection of light
on smooth surfaces such
as mirrors or a calm body
of water.

14. DIFFUSE/IRREGULAR
This is a reflection of light on
rough surfaces such as
clothing, paper, wavy water,
and the asphalt roadway.

15. EVALUATE
•What is the law of
reflection?
•What are the types of
reflection?

16. ASSIGNMENT
•Study about curved mirrors
and mirror equation.
