Question

If the length of the crest of a wave is 4pm. write the wavelength of this wave.

Answer 1

Answer:

Explanation:

Wavelenght  = 4pm x 2 = 8pm = 8(1 x 10^-12)metre

Answer 2

Given: crest of wave is 4 picometer.

To find: wavelength of the wave.

Step by step explanation:

Step 1 of 1

The crest of the wave can be expressed in meter as:

$1pm=10^{-12} m\\\\4pm=4*10^{-12} m$

The formula of wavelength in terms of crest is:

Wavelength = 2 x crest

Wavelength = $2*4*10^{-12} m=8*10^{-12} m$.

The wavelength of wave is $8*10^{-12} m$.
