A) Frequency, wavelength and velocity
B) Frequency and wavelength
C) Frequency and velocity
D) Wavelength and velocity
Correct Answer: D
Solution :
When light travels from one medium to another, it is deviated from its path. This phenomenon is called refraction. In refraction both the speed and wavelength of the waves are changed but the frequency remains unchanged. For refractive index \[_{1}{{\mu }_{2}}=\frac{{{v}_{1}}}{{{v}_{2}}}=\frac{speed\text{ }of\text{ }light\text{ }in\text{ }first\text{ }medium}{speed\text{ }of\text{ }light\text{ }in\text{ }second\text{ }medium}\]and \[_{1}{{\mu }_{2}}=\frac{\lambda }{{{\lambda }_{m}}}\]You need to login to perform this action.
