WebFirst law: According to the first law of refraction, the incident ray, the refracted ray and the normal at the point of incidence, all lie in the same plane. Second law: According to the second law of refraction, the ratio of the sine of angle of incidence to the sine of angle of refraction is constant for a given pair of media. WebA light ray traveling in water of refractive index 1.3 is incident on the flat surface of a plastic block with a refractive index of 1.7, hitting the surface at an angle of 45 degrees from the line normal to the surface. At what angle from the line normal to the surface does the refracted ray in the block travel? Answer to the nearest degree.

WebAnswer.(i) Angle of prism (ii) refractive index. Question. 24.What is dispersive power of prism? Answer.It is de ne as the ratio of the angular dispersion for these two colours to the mean deviation produced by the prism. Question. 25.What is factor on which dispersive power depends? Answer.It depends upon refractive index of the material of prism. WebCheck 'refraction' translations into Bangla.
