wavelength changes but frequency remains the same |
The correct answer is Option (2) → wavelength changes but frequency remains the same When light travels from one medium to another: - The speed of light changes due to change in refractive index. - Frequency remains constant, as it is determined by the source. - Wavelength changes according to $v = f \lambda$. Wavelength changes but frequency remains the same |
