I believe it is, since the heat causes the water to evaporate and cause condensation,
The body releases endorphins
Given:
f1 = 20 Hz
f2 = 20000 Hz
speed of sound at 20 degrees celcius = 343 m/s
Solution:
for f1 = 20 Hz,
Using the equation:
lambda = speed of sound / f1 = 343 / 20 = 17.15 m
For f2:
lambda = speed of sound / f2 = 343 / 20000 = 0.01775 m
Therefore the wavelength range of audible sound in air would be 17.15 m to 0.01775 m.
Answer: radio waves, microwaves, infrared waves.
Explanation:
Electromagnetic spectrum increases in wavelength and decreases with frequency in the following order
Gamma ray, X ray, Ultraviolet rays, Visible light, Infrared rays, Radio waves.
Since 397nm is greater than the value of visible spectrum, this shows that radio waves, microwaves and infrared wave falls in the spectrums of the wavelength value.
