RAY OPTICS CLASS XI
Q1)Does critical angle depend on wavelength used?
|
Q2)Does a prism displace
or deviate an incident ray?
|
Q3)What are the factors on which light reflected from a
surface depends?
|
Q4)A thin prism of 600 gives deviation of 300.
what is the refractive index of the material of the prism?

Q5)For what angle of incidence the lateral shift produced
by a parallel sided glass slab is maximum?
|
Q6)What will be the colour of the sky in the absence of
atmosphere?
|
Q7)How deep will a 4m tank appear when seen in air due to
optical illusion. Refractive index of water is 4/3.
|
Q8)Name the colour having the ( i ) minimum speed ( ii ) maximum speed through a prism.
|
Q9)Yellow light of wavelength 589nm is incident on a
boundary separating air and glass . Find the speed , wavelength and frequency
for ( i ) reflected light ( ii )
refracted light . Refractive index of glass for yellow light is 1.5
