Question on: WAEC Physics - 1994
A light wave travels from air into a medium of refractive index 1.54. If the wavelength of the light in air is (5.9\times10^{-7})m, calculate its wavelength in the medium
A
\(2.5\times10^{-7}\)m
B
\(3.8\times10^{-7}\)m
C
\(4.6\times10^{-7}\)m
D
\(5.2\times10^{-7}\)m
Ask EduPadi AI for a detailed answer
Correct Option: B
n =(\frac{wavelength, in, air}{wavelength, in ,medium}= \frac{5.9\times10^{-7}}{1.54}= 3.8\times10^{-7})m
