367819 When a photon enters glass from air, which one of the following quantity does not change?

1 Velocity
2 Wavelength
3 Momentum
4 Energy
PHXII10:WAVE OPTICS

367820 Assertion :
Radio waves can be polarised.
Reason :
Sound waves in air longitudinal in nature.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

367821 Light is incident normally on a diffraction grating through which the first diffraction is seen at \(32^{\circ}\). In this case, the second order diffraction will be

1 at \(80^{\circ}\)
2 at \(64^{\circ}\)
3 at \(48^{\circ}\)
4 there is no second order diffraction
