Reflection and Refraction

A ray of light with wavelength 5000 nm travelling from a medium with refractive index (3/2) suffers partial reflection and refraction in a medium of refractive index (4/3) . Find wavelength of reflected and refracted ray.

A ray of light from a denser medium strikes a rarer medium at an angle of incidence I (see figure ). The reflected and refracted rays make an angle of 90^(@) with each other. The angles of reflection and refraction are r and r^() . The critical angle is

A ray of light passes from a denser medium to a rarer medium at an angle of incidence i. The reflected and refracted rays make an angle of 90^@ with each other. The angle of reflection and refraction are resepectively r and r'. The critical angle is given by :

If a ray of light in a denser medium strikes a rarer medium at an angle of incidence i, the angles of reflection and refraction are respectively, r and r' If the reflected and refraction rays are at right angles to each other, the critical angle for the given pair of media is

A ray of light from a denser medium strikes a rarer medium at an angle of incidenc i. The reflected and refracted rays make an angle of pi//2 with each other. If the angles of reflection and refraction are r and r^(') , then the criticall angle will be

A ray of light from a denser medium strike a rarer medium at an angle of incidence I (see Fig). The reflected and refracted rays make as angle of 90degrees with each other. The angles of reflection and refraction are r and r The critical angle is

A ray of light of internsity I is incident on a parallel glass slab at a point A as shown. It undergoes partial reflection and refraction. At each reflection and refraction. At each rerflection 20% of incident energy is reflectrd. The rasys AB and A' B' undergo interference. The ratio I_(max)//I_(min) is
