A dye absorbs a photon of wavelength `lamda` and re-emits the same energy into two photons of wavelengths `lamda_(1)` and `lamda_(2)` respectively. The wavelength `lamda` is related with `lamda_(1)` and `lamda_(2)` as :

A

`lambda=(lambda_(1)+lambda_(2))/(lambda_(1)lambda_(2))`

B

`lambda=(lambda_(1)lambda_(2))/(lambda_(1)+lambda_(2))`

C

`lambda=(lambda_(1)^(2)lambda_(2)^(2))/(lambda_(1)+lambda_(2))`

D

`lambda=(lambda_(1)lambda_(2))/((lambda_(1)+lambda_(2))^(2))`

In a Young's double slit experiment with slit separation 0.1 mm, one observes a bright fringe at angle (1)/(40) rad by using light of wavelength lamda_(1). When the light of wavelength lamda_(2) is used a bright fringe is seen at the same angle in the same set up. Given that lamda_(1) and lamda_(2) are in visible range (380 nm to 740 nm), their values are :

Which graph shows how the energy E of a photon of light is related to its wavelengths (lamda) ?

The angles of incidence and refraction of a monochromatic ray of light of wavelength lamda at an air-glass interface are i and r, respectively. A parallel beam of light with a small spread delta lamda in wavelength about a mean wavelength lamda is refracted at the same air-glass interface. The refractive index mu of glass depends on the wavelength lamda as mu(lamda) = a + b//lamda2 where a and b are constants. Then the angular spread in the angle of refraction of the beam is
