Assuming that the tungsten filament of a lightbulb is a blackbody, determine its peak wavelength if its temperature is 3 200 K.

the peak wavelength when the temperature is 3200 K =

Explanation:

Given that:

the temperature = 3200 K

By applying  Wien's displacement law ,we have

T = 0.2898×10⁻² m.K

The peak wavelength of the emitted radiation at this temperature is given by

=

=

Hence, the peak wavelength when the temperature is 3200 K =

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

this could be newton#'s law of cooling. the cooling curve is exponential
