The temperature of the cosmic background radiation is measured to be 2.7 k. what is the wavelength of the peak in the spectral distribution at this temperature?

Explanation:

The peak wavelength of the spectral distribution can be found by using Wien's displacement law:

where

is Wien's displacement constant

T is the absolute temperature

For the cosmic background radiation, the temperature is

T = 2.7 K

So, the corresponding peak wavelength is

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
