Question

At what wavelength would a star radiate the greatest amount of energy if the star has a surface temperature of 60,000 K?

Answer 1

`\lambda=4.81* 10^(-8)\ m`

Step-by-step explanation:

We have,

The surface temperature of the star is 60,000 K

It is required to find the wavelength of a star that radiated greatest amount of energy. Wein's displacement law gives the relation between wavelength and temperature such that :

`\lambda T=2.89* 10^(-3)`

Here,

`\lambda` = wavelength

`\lambda=(2.89* 10^(-3))/(60000)\\\\\lambda=4.81* 10^(-8)\ m`

So, the wavelength of the star is
`4.81* 10^(-8)\ m`.
