As an example, a wave with a period T = 0.25 s takes ¼ of a second to complete a full vibration cycle (crest – trough – crest) at a certain location and thus performs four vibrations per second. Hence its frequency is f = 4 Hz.
What is the frequency of a wave that has a period of 0.5 seconds?
The “Time Period” is the time taken for one complete cycle of vibration to pass a specific point. As the frequency of a wave increases, the time period of the wave decreases and as the frequency of a wave decreases, the time period of the wave increases. So, the answer is, f = 1/0.5 = 2 Hz.
How do you find the frequency of a wave period?
The formula for frequency is: f (frequency) = 1 / T (period). f = c / λ = wave speed c (m/s) / wavelength λ (m).
What is the wave frequency when the period is 0.2 s?
If the woodpecker drums upon a tree 5 times in one second, then the frequency is 5 Hz, each drum must endure for one-fifth a second, so the period is 0.2 s.
What is the frequency of a wave with the period of 1 second?
The frequency of a wave is measured in Hertz.
1 Hertz equals 1/s – one cycle per second.

What is a period of a wave?
Wave Period: The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds, e.g. one wave every 6 seconds.
What is the period of a periodic wave that has a frequency of 60 hertz?
The time between two identical points on a sine wave is called the period, and at a frequency of 60Hz (60 cycles per second) there will be a period of approximately 16.6 milliseconds, as shown in the diagram.
How do u find the frequency?
To calculate frequency, divide the number of times the event occurs by the length of time. Example: Anna divides the number of website clicks (236) by the length of time (one hour, or 60 minutes). She finds that she receives 3.9 clicks per minute.
What is the period of a frequency?
The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times a minute (2 hertz), its period, T—the time interval between beats—is half a second (60 seconds divided by 120 beats).
What is the frequency of wave whose period is 0.02 seconds?
f = 50 Hz.
What is the frequency of the wave if its period is 8 seconds?
A frequency of 1 Hz corresponds to one complete wave passing a point each second. If 4 waves pass a point in 8 seconds then the frequency is: 48=12=0.5 Hz.
What is the frequency of a wave given that its period is about 0.01667 second?
What is the frequency of a wave, given that its period is about 0.01667 second? Answer: 60 Hz.

What is the frequency of a wave whose time period is 0.015 seconds?
= 66.66 Hz ans.
What is the frequency of 60 cycles per second?
60 cycles per second is equal to 60 Hertz. A thousand Hertz is often referred to as a Kilohertz (kHz). Frequency can also be measured in time where the duration of a given cycle is equal to its frequency, where a thousandth of a second is stated as a millisecond. One millisecond equals a Kilohertz.
What is the formula for period?
… each complete oscillation, called the period, is constant. The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.
What is the wavelength of a wave with a frequency of 262 Hz and a speed of 343 m s?
If the speed of sound is 343 m/s and a sound has a frequency of 262 Hz, what is its wave length? velocity = wavelength * freq. 343 ms–1 = wave length * 262 = 1.31 meters.
How do you calculate the wavelength of a wave?
How to calculate wavelength
- Determine the frequency of the wave. For example, f = 10 MHz . …
- Choose the velocity of the wave. …
- Substitute these values into the wavelength equation λ = v/f .
- Calculate the result. …
- You can also use this tool as a frequency calculator.
What is the frequency of a wave if 20 waves are produced in 4 seconds?
Hence, if 20 waves are produced per second then the frequency is 20 Hz.
What is the frequency of a vibration with period 2 second?
T is the time it takes for one complete oscillation , it is measured in seconds. All waves, including sound waves and electromagnetic waves , follow this equation. For example, a wave with a time period of 2 seconds has a frequency of 1 ÷ 2 = 0.5 Hz.
What is the frequency of a wave with a period of 3 s?
The period is 3 seconds so the frequency is 1 / T or 0.333 Hz.
What is the frequency in hertz or cycles per second of a wave that has a period of 10 seconds?
10 hertz just means 10 cycles per second. If my frequency is 10 cycles per second, my period is going to be 1 over that.
What is the frequency of a seismic wave with a period of 10 seconds 1 second and 0.25 second?
What is the frequency of a seismic wave with a period of 10 seconds 1 second and 0.25 second? The frequency of a seismic was with a period of 10 seconds is 0.1 Hz, the frequency of a seismic wave with a period of 1 second is 1 Hz and the frequency of a seismic was with a period of 0.25 seconds is 4 Hz.
What happens to the wavelength as the frequency increases *?
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
What is the frequency of a vibration with period 0.05 second?
Frequency = 20 Hz
Time period is the time taken to complete a cycle of any function while frequency is the number of times a cycle is completed each second. So given that the time period is 0.05 seconds, frequency of the vibration will be 1 / time period. Frequency = 20 Hertz.
