Question

A light beam has a frequency of 6 x 1015 Hz. What is its wavelength?

Answer 1

The wavelength of the light beam is 5.0 x 10^-8 meters.

Step-by-step explanation:

The wavelength of light can be calculated using the formula:

λ = c / v

Where λ is the wavelength, c is the speed of light, and v is the frequency.

Given that the frequency of the light beam is 6 x 1015 Hz, we can substitute the values into the formula:

λ = (3.0 x 10^8 m/s) / (6 x 10^15 Hz)

Calculating this expression gives us:

λ = 5.0 x 10^-8 m

Therefore, the wavelength of the light beam is 5.0 x 10^-8 meters.

Answer 2

Data: f=6*10^15 Hz

The relation between wavelength, speed and frequency of a light beam in the vacuum can be written as:

`c=\lambda f`

Thus, for our situation:

`\lambda=(c)/(f)=(3*10^8)/(6*10^(15))=5*10^(-8)m`

Thus, our wavelength will be 5*10^(-8)m or 50nm
