A single light beam is split into two equal beams, denoted A and B$.$ Beam A travels through a medium with a higher index of refraction than the medium that beam $B$ travel through. When both beams exit their media back into air, how do their wavelengths compare?

a$)$ Beam A has a longer wavelength.

b$)$ Beam $B$ has a longer wavelength.

${}_n=\frac{500}{100}=5$

${}_n=\frac{500}{10}=50$larr$1$ onser?

c$)$ Both beams have the same wavelength.A single light beam is split into two equal beams, denoted A and B$.$ Beam A travels through a medium with a higher index of refraction than the medium that beam $B$ travel through.
