One shot light class 10 term 1 ! light reflection and refraction class 10

Q_(10) of light reaction is

A parallel beam of light of intensity I is incident on a glass plate. 25% of light is reflected in any reflection by upper surface and 50% of light is reflected by any reflection from lower surface. Rest is refracted The ratio of maximum to minimum intensity in interference region of reflected rays is

Assertion :- When monochromatic light is incident on a surface separating two medium, the reflected and refracted light has same frequency as incident light. Reason :- Reflection and refraction arise through interaction of incident light with atoms of matter and atoms act as oscillator which takes up frequency of incident light and undergoes forced oscillation and scatters light of same frequency.

Refraction & Reflection of Light

A ray of light falls on a glass plate of refractive index mu=1.5 . What is the angle of incidence of the ray if the angle between the reflected and refracted rays is 90^@ ?

A ray of light falls on a glass plate of refractive index mu=1.5 . What is the angle of incidence of the ray if the angle between the reflected and refracted rays is 90^@ ?

Assertion : The frequencies of incident, reflected and refracted beam of monochromatic light are same. Reason : The incident, reflected and refracted rays are coplanar.

Let the refractive index of a denser medium with respect to a rarer medium be n_(12) and its critical angle be theta_(c) . At an angle of incidence A when light is travelling from denser medium to rarer medium, a part of the light is reflected and the rest is refracted and the angle between reflected and refracted rays is 90^(@) , Angle A given by -
