Hi there!
Recall the equation for weight.

W = Weight (N)
M = Mass (kg)
g = acceleration due to gravity (m/s²)
The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:

This is known as Wien's Law:
The relationship is:
wavelength = 0.0029/temperature
It is an inversely proportional relationship.
