Vedclass · Answer

(A) When light travels from a denser medium to a rarer medium,the refractive index of the second medium is lower than the first $(n_2 Since the speed of light $v$ in a medium is given by $v = c/n$,where $c$ is the speed of light in vacuum and $n$ is the refractive index,a decrease in $n$ leads to an increase in the speed of light ($v$ increases).The frequency $f$ of light remains constant during refraction because it depends only on the source.The relationship between speed,frequency,and wavelength is given by $v = f \lambda$.Since $v$ increases and $f$ remains constant,the wavelength $\lambda$ must also increase $(\lambda = v/f)$.

What is the effect on the speed and wavelength of light when a light wave is refracted from a denser medium to a rarer medium?
