How do you calculate how long a wave takes to travel?
How can I calculate the speed of an ocean wave? Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.
How long will it take for sound wave of 25 cm wavelength and 1.5 Khz frequency of to travel a distance of 1.5 km?
Wavelength = 25 cm = 0.25 meters. If the sound travels 375 meters in one second, How much time will it take to travel 1500m? Therefore the sound wave will take 4seconds to travel 1.5 kms.
What is the intensity of a wave?
The intensity (I) of a wave is defined as the rate at which it transfers energy divided by the area over which the energy is spread. In other words, intensity is the rate of energy flow per unit area.
What is the wavelength of a wave if it has a frequency of 40 hertz and a speed of 120 m s?
The wavelength is 2.5 m.
What is the speed of a wave if it has a frequency of 40 Hz and wavelength of 50m?
100 meters per second
The distance from one crest to the next is called the wavelength, Wavelength can also be measured from trough to trough or from any point on the wave to the next place where that point occurs. The frequency of a wave is 40 Hz and its speed is 100 meters per second.
What is the length of a sound wave?
A sound wave has a frequency 2 Hz and a wave length 40 cm. How long will it take to travel 1.6 km? – Quora A sound wave has a frequency 2 Hz and a wave length 40 cm. How long will it take to travel 1.6 km?
What is the wavelength of a 20 Hz wave?
If we use 20 Hz. as our frequency, we take the speed of sound 1130 ft./sec. and divide it by 20. Our answer is 56.5 ft. This means that a 20 Hz. wave has a wavelength of 56.5′.
How do you find the velocity of a wave using frequency?
For finding the velocity of wave when frequency and wave length is given, you ca use the relation v= (wavelength (in meter)* frequency) .It will give you the result of 0.8 m/s. The key for solving every problem in physics is the converison of units to SI units.
How is sound energy divided into frequencies?
Sound energy is divided into frequencies. Each frequency has a given size or length. The speed of sound, 1130 ft./sec., stays constant and is used to calculate the length of a particular frequency.
