The refractive index of a medium is 3 If the unpolarised light is incident on it from air at the polarizing angle of the medium the angle of refraction is NCERT Pg 379 1 60 2 45 3 30 4 0 17 When interference of light waves takes place NCERT Pg 361 1 Energy is created in the region of maximum intensity 2 Energy is destroyed in the region of minimum intensity 3 Conservation of energy hold good and energy is redistributed 4 Conservation of energy does not hold good Two points separated by a distance of 0 1 mm can just be inspected in a microscope when light of wave length 6000 is used If the light of wavelength of 8000 A is used then the limit of resolution will be NCERT Pg 373 1 0 8 mm 2 1 2 mm 3 0 1 mm 4 0 13 mm 19 Transverse nature of light was confirmed by NCERT Pg 376 the phenomena of 1 Reflection of light 2 Diffraction of light 3 Interference of light 4 Polarisation of light A light of wavelength 550 nm coming from a distant star The limit of resolution of a telescope whose objective has a diameter of 2 mis NCERT Pg 373 20 1 3 38 x 10 7 rad 2 3 35 x 10 5 rad 3 3 35 x 10 6 rad 4 2 15 x 10 7 rad
