A prism of refractive index n_(1) and another prism of refractive index n_(2) are stuck together (as shown in the figure). n_(1) and n_(2) depend on lambda , the wavelength of light, according to the relation n_(1)=1.2 +(10.8 xx 10^(-14))/(lambda^(2)) and n_(2)=1.45 +(1.8 xx 10^(-14))/(lambda^(2)) The wavelength for which rays incident at any angle on the interface BC pass through without bending at that interface will be _________ nm.

x ^(2) (lamda ^(2) - 4 lamda + 3) +y ^(2) (lamda ^(2) - 6 lamda +5) =1 will represent an ellipse if lamda lies in the interval

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

If line (2x-4)/(lamda)=(lamda-1)/(2)=(z-3)/(1) and (x-1)/(1)=(3y-1)/(lamda)=(z-2)/(1) are perpendicular to each then lamda= . . .

lamda_1, lamda_2, lamda_3 are the first 3 lines of balmer series. Find lamda_1//lamda_3

If the lines (1 -x )/(3) = ( 7y - 14)/(2 lamda) = (z - 3)/(2) "and" (7 - 7x)/(3lamda) = (y - 5)/(1) = ( 6 - z ) /(5) are at right angle, then the value of lamda is

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

Assertion : Two particles of de Broglie wavelength lamda_1 and lamda_2 combine to form a third particle of wavelength lamda_3 . Then , lamda_1 +lamda_2 =lamda_3 . Reason : If p_1,p_2 and p_3 are momenta of the three particles , respectively, then p_1+p_2=p_3 .
