5. Transverse waves oscillate in the z-y plane but travel along the x axis. A transverse wave has a speed of propagation given by the equation v = fλ. The direction of energy transfer is perpendicular to the motion of the wave. Transverse Waves Free to share, print, make copies and changes.

6. The reflected wave is inverted from the incident wave when a transverse wave on a string is fixed at the end point. The reflected wave is not inverted from the incident wave when a transverse wave on a string is free at the end point. A standing wave occurs when an incident wave meets a reflected wave on a string. A standing wave contains nodes (points that remain flat due to the destructive interference) and antinodes (points with maximum oscillation due to the constructive interference). Every point in the string oscillates up and down and the amplitude of the oscillations depends on the location of the point. A standing wave has some points that remain flat due to destructive interference. These are called antinodes. The points on a standing wave that have reached maximum oscillation do so from constructive interference, and are called nodes.

7. When a transverse wave on a string is fixed at the end point, the reflected wave is inverted from the incident wave. When a transverse wave on a string is free at the end point, the reflected wave is not inverted from the incident wave. A standing wave occurs when an incident wave meets a reflected wave on a string. The points in a standing wave that appear to remain flat and do not move are called nodes. The points which reach the maximum oscillation height are called antinodes. Every point in the medium containing a standing wave oscillates up and down and the amplitude of the oscillations depends on the location of the point. A standing wave has some points that remain flat due to destructive interference. These are called antinodes. The points on a standing wave that have reached maximum oscillation do so from constructive interference, and are called nodes. Reflections Free to share, print, make copies and changes.

9. Key terms amplitude The maximum absolute value of some quantity that varies. constructive interference Occurs when waves interfere with each other crest to crest and the waves are exactly in phase with each other. crest The ridge or top of a wave. destructive interference Occurs when waves interfere with each other crest to trough (peak to valley) and are exactly out of phase with each other. direction of propagation The axis along which the wave travels. speed of propagation The speed at which a wave moves through a medium. standing wave A wave form which occurs in a limited, fixed medium in such a way that the reflected wave coincides with the produced wave. A common example is the vibration of the strings on a musical stringed instrument. transverse wave Any wave in which the direction of disturbance is perpendicular to the direction of travel. trough A long, narrow depression between waves or ridges. wavelength The length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next; it is often designated in physics as λ, and corresponds to the velocity of the wave divided by its frequency.

13. Standing Wave on a String This is what a standing wave would look like if you were to slow it down. The wave is caused by an incident wave on a string being reflected and then traveling back in the direction it came from. The two waves then meet and interfere with each other causing this phenomenon. Free to share, print, make copies and changes. Get yours at www.boundless.com Wikipedia. "Standing wave."
