Answer:
Q2: (i) 75°
(ii) 45°
(iii) 90°
Q3: (i) 1m
(ii) 80 cm
Explanation:
Q2 (i) Angle of incidence is always equal to the angle of reflection. This is a property of a plain mirror. So, here,
angle of incidence = angle of reflection =x
x+30+x=180
2x=180-30
x=150/2
x=75°
(ii) Here, clearly the angle of incidence is marked as 45°
(iii) Here, angle of incidence is a right angle, i. e., 90°
Q3 (i) The height of the image always remains the same as the height of the object. So, it will be 1m.
(ii) The image is situated at the same distance behind the mirror as the object is situated in front of the mirror. So, here,
distance of object from mirror=40cm
distance of image from mirror=40cm
distance between object and image=40+40
=80cm
