Answer:

Planks law:

   Planks law gives the theoretical distribution for emissive power of black body.The emissive power for is given as follows

Planks distribution as a function of wavelength for different temperature.

E_{\lambda,b}=\dfrac{C_1}{\lambda^5 [exp{\frac{C_2}{\lambda T}-1}]}

Where C_1 andC_2 is the constant.

Important points for Planks distribution

1.At the given wavelength when temperature increases then emissive power will increase.

2.When temperature is increases then then distribution shift towards the left side.

3. We can assume that sun as a black body at  5800 K.
