What is the formula for calculating the frequency of a wave?
- Frequency = wavelength * amplitude
- Frequency = energy/time
- Frequency = number of waves/time (correct)
- Frequency = speed/distance
What is the relationship between sound intensity and distance from the source?
What is the relationship between sound intensity and distance from the source?
- The intensity of sound varies linearly with the distance from the source
- The intensity of sound varies directly with the distance from the source
- The intensity of sound is independent of the distance from the source
- The intensity of sound varies inversely with the square of the distance from the source (correct)
