Question

Q-2. Answer the following questions:
(a) Name the instruments which use the properties of reflection of light.
(b) What type of image do we see in a mirror? What happens to the left and right sides?
What angle will the reflected ray make with the mirror if the angle of incidence is 557
Give scientific reason: We do not see image in transparent glass.
Q.3. Answer the following questions:
Draw a figure showing the following.
(a) Incident ray (b) Normal (c) Angle of incidence
Write the Laws of reflection.
Study the following incident:
(1)
(2)
(3)​

Answer 1

a. optical instruments

b. if the image is in mirror then it is virtual image and in virtual image your left side becomes right and your right side becomes left. Since angle of incidence is equal to angle of reflected ray, therefore angle of reflected ray =557
