Question

wavelength of a ray of light in medium x is 700nm and medium y is 600 nm what is the refractive index of medium y with respect to medium x?

Answer 1

Wavelength and refractive index are inversely proportional. So do it in thst way

Answer 2

wave length of x = 700nm
while wavelength of y = 600nm
hence refractive index of y with respect to x =
wave length in x ÷ wavelength in y
=>600÷700= 6/7
