## Wavelength Calculator :

Enter the wavelength calculator, calculates the Wave velocity in meters per second(m/s), Wave frequency in hertz(Hz), Wavelength (λ) in meters(m), and you get the Calculation below the calculator.

## Wavelength Formula :

Wave length formula λ_{(m)} in meter is equal to the velocity of the wave v_{(m/s)} in meter per second and divided by frequency f _{(Hz)} in Hertz and wave length formula can be written as

**λ _{(m)}=v_{(m/s)}/f _{(Hz)}**

Where,

V→ velocity of the wave in m/s

F→ frequency in Hz

## Sample Sums :

## Sum1 :

Calculate the wavelength of the wave? in a harmonic wave is moving along a rope and the source generating the waves completes 30 to and formations in 40s.A through travels 2m in 5s .

### Answer:

Time taken for 30 oscillations =40s

Time for 1 oscillation t=30/40=0.75s

Frequency of 1 oscillation f=1/0.75=1.33HZ

The wave travels a distance of 2m in 5s

The wave speed is calculated by v=2/5=0.4ms^{-1}

The wavelength formula is given by byλ=v/f

=0.4/1.33

λ=0.30m

## Sum2 :

Calculate the wavelength of sound? In a frequency of a tunning fork is 400Hz and sound travels a distance of 40m while tuning fork executes 50vibrations.

### Answer:

Given,

Frequency f=400Hz

Distance d=40m

No of vibrations/oscillations=50

Wavelength λ=Distance/No of oscillations

=40/50

λ=0.8ms^{-1}
