Ray Optics and ...

A mark on the bottom of the liquid appears to rise by 0.1 m. The depth of the liquid is 1 m. The refractive index of the liquid is ​

Dispersive power is dependent on

Which is the position of minimum deviation in prism?

The ratio of angular dispersion of to the angle of deviation for the mean wavelength is called Dispersive Power. Represented by

Angle of dispersion depends on

Which relation do we use to find the refractive index of material of prism  

A prism of refractive index √2 and refractive angle A produces minimum deviation δm of a ray on one face at an angle of incidence 45 °. The values of A and δm are respectively ​

What is dispersive power?

A thin prism P₁  with angle 4 °and made from glass of refractive index 1.54 is combined with another thin prism P₂  made from glass of refractive index 1.72 to produce dispersion without deviation . The angle of prism P₂  is:​
