PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

365134 The reddish appearance of the sun at sunrise and sunset is due to

1 The polarisation of light
2 The scattering of light
3 The colour of the sky
4 The colour of the sun
PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

365135 Assertion :
The sun rises some time before the actual sun-rise.
Reason :
During sun rise, the refraction takes place through the different layers of atmosphere.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

365136 Assertion :
A secondary rainbow have inverted colours than the primary rainbow.
Reason :
The secondary rainbow is formed by single total internal reflection.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

365137 Statement A :
Sunlight reaches us without dispersion in the form of white light and not as its components.
Statement B :
Dispersion takes place due to variation of refractive index for different wavelength but in vacuum the speed of light is independent of wavelength and hence vacuum is a non-dispersive medium.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
