(a) Monochromatic light of wevelengh 589 nm in incident from air on a water surface. If mu for water is 1.33, find the wevelength, frequency and speed of the refracted light . (b) A duble conbex lens is made of a glass of refractive index 1.55 , with both faces of the same radius of curbature. Find the radius of curvature required , if the focal length is 20 cm.

A monochromatic light of wavelength 500 nm travelling in air strikes a glass surfaces. Calculate the wavelength, frequency and speed of refracted light. Take mu_("glass") = 1.5 .

A monochromatic light of wavelength lamda is incident ofn plane reflecting surface. After reflection, its wavelength will be

Monochromatic light of wavelength 589nm is incident from air on a water surface. Given, refractive index of water is 1.33. Which of the following statement(s) is/are correct? I. Frequency of reflected light and refracted light are same. II. Wavelength of reflected light is more than that of refracted light. III. Speed of reflected light is equal to that of refracted light. IV. Intensity of reflected light is always more than that of refracted light.

Monochromatic light is refracted from air into the glass of refractive index mu . The ratio of the wavelength of incident and refracted waves is
