Calculate the intensity of thermal radiation from a blackbody by using raleigh-jeans law at a temperature of 1000 k and with a wavelength of 1000 nm (infrared), 500 nm (visible), and 100 nm (ultraviolet). (3 points) (b) recalculate the above intensities using plank's law

Explanation:

Given that,

Temperature = 1000 K

We need to calculate the  intensity of thermal radiation from a black body

For wavelength 1000 nm

Using Raleigh-Jeans Law

Put the value into the formula

For wavelength 500 nm

For wavelength 100 nm

We need to calculate the intensity

Using Plank's Law

For wavelength 1000 nm

Put the value into the formula

For wavelength 500 nm

For wavelength 100 nm

Hence, This is the required solution.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
