Superposition and Reflection of Waves

Two transverse waves overlap.  Crests overlap with troughs.  Troughs overlap with crests.  The waves are

• In-phase
• Out-of-phase
• In-synchronicity
• Out-of-synchronicity

If two overlapping waves are in-phase, the resultant wave will have ______ compared to the two waves.

• Greater amplitude
• Greater frequency
• Greater wavelength
• Greater wave speed

What is the superposition of waves?

• when a single wave splits into two different waves at a point
• when two waves combine at the same place at the same time

What are standing waves?

• waves that appear to remain in one place and do not seem to move
• waves that seem to move along a trajectory

Standing waves are formed --

• by the superposition of two or more waves moving in opposite directions.
• by the superposition of two or more waves moving in the same direction.
• by the superposition of two or more waves moving in perpendicular directions.
• by the superposition of two or more waves moving in any arbitrary directions.

A stretched string is observed to have four equal segments in a standing wave driven at a frequency of 480 Hz.  What driving frequency will set up a standing wave with five equal segments?

• 600 Hz
• 360 Hz
• 240 Hz
