Question

9) A ray of light is incident on the minor Mi aso shown in figure then the angle of reflection of light ray surface of minor M2 is Light ray on the Incident light ray 120​

Answer 1

Answer:

In physics, a force is any influence that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Answer 2

Answer:

Since angle of incident =angle of reflection

Hence r=30

0

And here angle of deviation,

δ=180

0

−(i+r)

δ=120

0
