Ans: a
Exp: A: The relationship between refractive index \((\mu)\) and wavelength \((\lambda)\) is described by a curve known as the dispersion curve. The dispersion curve shows how the reflective index of material changes with respect to wavelength of light. Typically, the refractive index of material decreases as the wavelength of light increases. This means that longer wavelength, such as red light, will be bent less than shorter wavelength such as violet light.

282701 The refractive index of the material of the prism and liquid are 1.56 and 1.32 , respectively. When will be the value of \(\theta\) for the above refraction?

282702 If refractive index of a material of equilateral prism is \(\sqrt{3}\), then angle of minimum deviation of the prism is
