The absolute refractive indices of two media 'A' and 'B' are 2.0 and 1.5 respectively. If the speed of light in medium 'B' is `2xx10^8 m/s`, calculate the speed of light in
Medium 'A'

The refractive index of glass is 1.5 and that of water is 1.3.If the speed of light in water is 2.25 xx 10^8 m s^(-1) ,what is the speed of light in glass?

For the same angle of incidence, the angle of refraction in three different media A, B and C are 15^@, 25^@ and 35^@ respectively. In which medium will the velocity of light be minimum ?

Two satellites A and B go round a planet in circular orbits R and 2R respectively.If the speed of satellite A is 4 v ,then what will be the speed of satellite B?

For the same angle of incidence,the angles of refraction in three different mediaA,B and C are 15^@,25^@ and 35^@ respectively.In which medium will the velocity of light be minimum?

A planet is revolving round the sun in elliptical orbit. The maximum and minimum distances of the planet from the sun are 2 xx 10^2 m and 2 xx 10^10 m respectively. The speed of the planet when it is nearest to sun is 2 xx 10^15 ms^-1 What is the speed when it is farthest to the sun?
