365018 Read the Assertion and Reason carefully to mark the correct options given below:
Assertion :
The phase difference of two light waves change if they travel through different media having same thickness, but different indices of refraction.
Reason :
The wavelengths of waves are different in different media.

1 Both Assertion and Reason are correct but Reason is NOT the correct explanation of Assertion.
2 Assertion is not correct but Reason is correct.
3 Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
4 Assertion is correct but Reason is not correct.

365019 A ray of light passes from glass having a refractive index of 1.6, to air. The angle of incidence for which the angle of refraction is twice the angle of incidence is

1 \({\sin ^{ - 1}}\left( {\frac{3}{5}} \right)\)
2 \({\sin ^{ - 1}}\left( {\frac{4}{5}} \right)\)
3 \({\sin ^{ - 1}}\left( {\frac{2}{5}} \right)\)
4 \({\sin ^{ - 1}}\left( {\frac{5}{8}} \right)\)

365020 A ray of light is travelling from glass to air. (Refractive index of glass = 1.5). The angle of incidence is \({50^o}\). The deviation of the ray is

1 \({0^o}\)
2 \({80^o}\)
3 \({50^o} - {\sin ^{ - 1}}\left[ {\frac{{\sin {{50}^o}}}{{1.5}}} \right]\)
4 \({\sin ^{ - 1}}\left[ {\frac{{\sin {{50}^o}}}{{1.5}}} \right] - {50^o}\)
