What is the speed of a wave with a frequency of 760 Hz and a wavelength of 0.45 m? | 342 m/s |
A wave has a speed of 330 m/s. Its wavelength is 15 m. Calculate the frequency of the wave? | 22hz |
Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.
Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium. Hence, the wavelength of the sound wave is 2 m.
150 cm
Answer. Answer: The answer is 1 m. Thus the wavelength of the sound is 1 m.
vacuum
Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. The speed of sound at room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures.
about 343 metres per second
