If light falls on a plane mirror at an angle of incidence 30°, then find the deviation suffered by a

light ray ?

Answers

Explanation:

The correct option is (C) 120°.

Explanation:

Angle of deviation when a ray is incident at angle (i) for a plane mirror, is given by δ = 180 – 2i

here i = 30°

∴ δ = 180 – (2 × 30) = 120°

What viscosity must this liquid have for both Reynolds and Froude model laws to be satisfied? At what speed must the model be towed? If 117.7 watts is required to tow the model at this speed, what power is required by the ship?
