When a light wave passes from air through matter, such as a piece of glass, . Select all that apply. When a light wave passes from air through matter, such as a piece of glass, . Select all that apply. the frequency increases the frequency decreases the speed increases the speed decreases the wavelength increases the wavelength decreases

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
