Explain the difference between the regular and irregular reflection of light.

Draw a figure describing the following. The reflecting surfaces of two mirrors make an angle of 90⁰ with each other. If a ray incident of one mirror has an angle of incidence of 30⁰ , draw the ray reflected from the second mirror. What will be its angle of reflection?

How will you explain the statement ‘we cannot see the objects in a dark room’?

Draw a figure showing the following.

a. Incident Ray

b. Normal

c. Angle of incidence

d. Angle of reflection

e. Point of incidence

f. Reflected ray

Study the following incident. Swara and Yash were looking in a water filled vessel. They could see their images clearly in the still water. At that instant, Yash threw a stone in the water. Now their images were blurred. Swara could not understand the reason for the blurring of the images. Explain the reason for blurring of the images to Swara by answering the following question.

i. Is there a relation between the reflection of light and the blurring of the images?

ii. Which types of reflection of light can you notice from this?

iii. Are laws of reflection followed in these types of reflection?
