A beam of light of wavelength `400 nm` is incident normally on a right angled prism as shown in Fig.
It is observed that light just grazes along the surface `AC` after falling on it. If refractive index `mu` of the material of prism varies with wavelength
`lamda` as `mu = 1.2 + (b)/(lamda^2)`
Calculate the value of `b and mu` of prism material for `lamda = 500 nm`. Given `theta = sin^-1 (0.625)`.

A beam of light of wavelength 400 nm is incident normally on a right angled prism as shown in fir.2.45. . It is observed that the light just grazes long the surface AC after falling on it.Give that there fractive index of the material of the prism varies with the wavelength as per the relation. mu=1.2 + b/(gamma^2) Calculate the value of b and the refractive index of the prism material for a wavelength gamma = 500 nm .Given theta=sin^(-1) 0.625 .

A ray of light is incident horizontally on the face AB of the.right angled prism as shown in the figure. If the ray emerges grazing the surface AC, find the value of phi . Refractive index of the material of the prism is given to be n.

According to Cauchy's formula, the refractive index mu of a material is related to wavelength lamda as………. .

A monochromatic ray of light is incident normally on one of the refracting surfaces of a prism . The emergent ray grazes the second refracting surface . What is the angle of the prism if the refractive index of the material of the prism is 1.6 ?
