4 cards from this section. Quick, good the night before a test.
Define amplitude in the context of waves.
Think about how high a wave goes from its calm state.
What is the formula to calculate wave speed?
It involves frequency and wavelength.
What is the formula for wave speed?
Remember how each component relates to waves.
True or False: Electromagnetic waves require a medium to travel.
Consider whether the wave needs something to move through.
A sound wave in air at 25 degrees Celsius travels at a speed of about 346 m/s. If the temperature increases to 35 degrees Celsius, what will be the new speed of sound?
Alter T in the formula to reflect the new temperature.
Two sound waves meet: one with a frequency of 400 Hz and another with 600 Hz. What is the effect of their interference at the point where they meet?
Consider phase alignment in wave characteristics.
