NCERT Exercise 10.1 - Wave Optics
Question: Monochromatic light of wavelength 589 nm is incident from air on a water surface. What are the wavelength, frequency and speed of (a) reflected, and (b) refracted light? Refractive index of water is 1.33.
Answer: **NCERT answer:** (a) Reflected light: (wavelength, frequency, speed same as incident light) l = 589 nm, n = 5.09 × 1014 Hz, c = 3.00 × 108 m s–1 (b) Refracted light: (frequency same as the inciden...
