Practicing Success
Case : Read the passage and answer the question(s). The properties of a light such as its speed, frequency and wavelength and properties of the medium like its refractive index give us a lot of information about the interaction of light with that medium. Consider a monochromatic ray of light travelling in vacuum with speed c, wavelength λ and frequency v, enters into a medium of refractive index 1.5. |
What will be its new frequency? |
2v v/3 v/2 same |
same |
Frequency remains unchanged in refraction. |
