Question

What is the temperature of a star whose maximum light is emitted at a wavelength of 290 nm?

Answer 1

Temperature, T = 10000 K

Step-by-step explanation:

It is given that,

Wavelength,
`\lambda=290\ nm=290* 10^(-9)\ m`

We need to find the temperature of a star whose maximum light is emitted at this wavelength. It can be calculated using Wein's displacement law as :

`\lambda_(max).T=2.9* 10^(-3)`

`T=(2.9* 10^(-3))/(290* 10^(-9))`

T = 10000 K

So, the temperature of a star is 10000 K. Hence, this is the required solution.
