When unpolarised light is incident on a plane glass at Brewster's angle, then which of the following statements is correct?


Important Questions on Wave Theory of Light
Figure represents a glass plate placed vertically on a horizontal table with a beam of unpolarised light falling on its surface at the polarising angle of with the normal. The electric vector in the reflected light on screen will vibrate with respect to the plane of incidence in a



The observed wavelength of light coming from a distant galaxy is found to be increased by $0.5 \%$ as compared with that coming from a terrestrial source. The galaxy is,

A star producing light of wavelength moves away from the earth with a speed of . Due to Doppler effect, the shift in wavelength will be, ,

A rocket is moving away from the earth at a speed of . The rocket has blue light in it. What will be the wavelength of light recorded by an observer on the earth? (Wavelength of blue light.)

A spectral line $\lambda=5000$ in the light coming from a distant star is observed as . What will be recession velocity of the star?

A star moves away from earth at speed while emitting light of frequency . What frequency will be observed on the earth in units of speed of light)
