Question

YESPYQ · Accepted Answer

Correct answer: wavelength and velocity. When light waves pass from air to glass, the wavelength and velocity are affected. Velocity decreases because the speed of light in glass is less than in air due to the higher refractive index of glass. Wavelength also decreases because it is directly proportional to the velocity of light in the medium (λ=v/f, where ‘f’ is the frequency). Frequency remains unchanged because it is determined by the source of the light and does not depend on the medium. Science and Technology 593 264
