the wavelength of lights into liquids x'and y'is 3500a and 7000athan the critical angle of xrelative to y will be
Hello!!!
Hope you are doing great!!!!
Given that
The wave length of light in X is 3500 Angstrom
The wave length of light in Y is 7000 Angstrom
Critical Angle = C ?
The critical angle C is given by :
Sin C =n2/n1
λ 1/ λ 2 = 3500/7000
sin C=0.5
C=30 degrees
Hope it helps!!!!
Good luck!!!!
