The intensity of X- ray from a coolidge tube is plotted againest wavelength lambda as shown in the figure . The minimum wavelength found lambda_(c) and the wavelength of the k_(a) line is lambda_(k) , As the accelerating voliage is increase

Which has a higher energy, a photon of violet light with wavelength 4000 A ˚ or a photon of red light with wavelength 7000 A ˚ ?

A : Young.s double slit experiment can be performed using a source of white light. R : The wavelength of red light is less than the wavelength of other colours in white light.

Light from a sources emitting two wavelengths lambda_(1) and lambda_(2) is allowed to fall on Young's double-slit apparatus after filtering one of the wavelengths. The position of interference maxima is noted. When the filter is removed both the wavelengths are incident and it is found that maximum intensity is produced where the fourth maxima occured previously. If the other wavelength if filtered, at the same location the third maxima is found. What is the raito of wavelength?

In an interference pattern the (n+4)^(th) blue bright fringe and n^(th) red bright fringe are formed at the same spot. If red and blue light have the wavelength of 7800Å and 5200 Å then value of n should be-

A beam of light consisting of red, green, and blue colors is incident on a right-angled prism. The refractive indices of the material of the prism for the above red, green and blue wavelengths are 1.39, 1.44 and 1.47, repectively. The prism will
