How does changing the wavelength affects the frequency of a wave?
The wavelength changes inversely with the frequency.
How does changing the frequency of the wave affect wavelength?
The wavelength changes inversely with the frequency.
How does the changing the frequency affect the energy of the wave?
Higher frequency increases the energy. Lower frequency decreases the energy.
How do you get different pitches?
By changing the frequency of the vibration. High frequency = high pitch. Low frequency = low pitch.
What is changing amplitude or frequency called?
modulation
Does changing the frequency change the amplitude?
In respect to what? But frequency is different than amplitude, so no.
