Q965
Energy in reflected light :
A.
Does not depends on the angle of incidence
B.
Increases with the increase in angle
AnswerC.
Decreases with the increase in angle of incidence
D.
Becomes maximum for angle of incidence equal to 45°
Answer: Option B
Solution
Answer: Option B
Solution:
Reflected waves are simply those waves that are neither transmitted nor absorbed, but are reflected from the surface of the medium they encounter. The amount of incident-wave energy that is reflected from a surface depends on the nature of the surface and the angle at which the wave strikes the surface. The amount of wave energy reflected increases as the angle of incidence increases. The reflection of energy is the greatest when the wave is nearly parallel to the reflecting surface.
