Question

1. If the refraction angle of the light transmitting from material 1 to material 2 is smaller than the incidence angle, which of the following statements are true? (More than one answer correct)
   1. The light will have slower speed in material 2 than in material 1.
   2. The light will have greater speed in material 2 than in material 1.
   3. The photon energy of the light is greater in material 2 than material 1.
   4. The photon energy of the light is less in material 2 than material 1.
   5. The frequency of the light is the same in both materials.

Answer 1

If the refraction angle in material 2 is smaller than the incident angle in material 1,it means material 2 is denser and materia 1 is rarer.

So the speed of light in material 2 will be slower than speed in material 1 as we know that the speed is less in denser medium and more in rarer medium.

The photon energy depends upon only frequency(E=hf) of light and frequency of light never changes so the photon energy in both materails will be same.

So the correct options are:(A), (E)
