1.	a light wave is incident on fixed plane mirror. this mirror starts rotating with angular acceleration of 360 rad/s2. so who is the reflected wave after 0.25 sec?
Answer» Answer: Angle TURNED by ray = twice of ANGULAR DISPLACEMENT $= 2 \times \frac{1}{2} \pi \times ( \frac{1}{4} ) {}^{2}$ $= 11.25$

Answer:

Angle TURNED by ray = twice of ANGULAR DISPLACEMENT

$= 2 \times \frac{1}{2} \pi \times ( \frac{1}{4} ) {}^{2}$

$= 11.25$
