Explain.
1 - frequency
2 - wave length
3 - Audible sound
Answers
Explanation:
1.Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. ... The hertz measurement, abbreviated Hz, is the number of waves that pass by per second.
2.The wavelength (λ) is defined as the distance between any two consecutive identical points on the waveform. ... The wavelength of a wave is the distance between any two corresponding points on adjacent waves. It is easiest to visualize the wavelength of a wave as the distance from one wave crest to the next.
3.Audible sound: The human ear can only recognize sounds of frequencies in the range of 20 Hz and 20,000 Hz and this range of frequency is called audible sound. ... Sounds of frequencies less than 20 Hz are called infrasonic sounds, while sounds of frequencies greater than 20,000 Hz are called subsonic or ultrasonic sounds.
Answer:
Frequencies is the number of occurrences of a repeating event per unit of time.
The distance between two sound waves called wave length.
