Question

The temperature of the hot spots caused by the impact of transferred matter onto the surface of a pulsar can be 108 K. What is the peak wavelength in the blackbody spectrum of such a spot, and in what range of the electromagnetic spectrum does it occur

Answer 1

Given that,

Temperature = 10⁸ K

We need to calculate the peak wavelength in the blackbody spectrum

Using formula of peak wavelength

`peak\ wavelength = (2.898*10^(-3))/(T)`

Where, T= temperature

Put the value into the formula

`peak\ wavelength = (2.898*10^(-3))/(10^(8))`

`peak\ wavelength = 2.90*10^(-11)\ m`

`peak\ wavelength = 290\ nm`

This range of wavelength is ultraviolet.

Hence, The peak wavelength in the blackbody spectrum is 290 nm and the range of wavelength is ultraviolet electromagnetic spectrum .
