Question on: WAEC Physics - 2001
An incident ray is reflected normally by a plane mirror onto a screen where it forms a bright spot. The mirror and screen are parallel and 1m apart. If the mirror is rotated through 5o, calculate the displacement of the spot
A
8.7cm
B
10.0cm
C
15.4cm
D
17.6cm
Ask EduPadi AI for a detailed answer
Correct Option: D
tan 10o = \(\frac{x}{1}\)
x = 1 tan 10o = 0.176m
= 17.6cm
x = 1 tan 10o = 0.176m
= 17.6cm
