Two students stand 6 meters apart and demonstrate the motion of a transverse wave on a slinky. The wave can be described as having a vertical distance of 18 cm from the top of a crest to the bottom of a trough. The waves have a horizontal distance of 48 cm from a crest to the nearest trough when the frequency is 0.5 Hz. Find the amplitude (cm), amplitude time period (seconds), wavelength (cm) and the speed of the wavelength (cm/second).

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.
