Answer 1

As shown in the figure when the Ray of light is incident to platform M1 it makes an Angle of 40° with the platform , Now if we take a Normal for this Incident Ray then the angle between the normal and the platform will be 90° as per LAWS OF REFLECTION

Now we can find the Angle Of Incidence by Subtracting 90° to the 40° Angle which is formed between the incident Ray and the platform

By doing this , we get :- 90° - 40° = 50°

Here we get the Angle Of Incidence as 50°

And now as shown in the figure , both the platforms are placed perpendicular to each other, Hence , the same Angle of incidence will form on the M2 platform

Hence the Angle of Incidence of M2 with the Given ray is 50°

Hope it helped...

Answer 2

Raman effect, change in the wavelength of light that occurs when a light beam is deflected by molecules. When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam.
