Please help me with the following Astronomy Questions?

Question

Wien's Law is a relation between the TEMPERATURE of an object and the PEAK EMISSION WAVELENGHT of the Continuous Spectrum emitted by the object.
Where the value of the constant depends on the units used for the wavelenght. If the unit used is Angstroms for the wavelenght, Wien's law is given by [lamboa]peak * T = 30,000,000 A more precise value would be 29, 000, 000 but the value has been rounded for simplicity. The temperature is given in Kelvin. Given this form of Wien's Law, complete table 1.

Table 1 Looks like this (Please help me to answer it)

Wavelenght (Angstroms) Temperature (K)
___________________ 1,500
____________________ 7,500
____________________ 20,000
____________________ 60,000
15,000 ________________
5,000 ________________
4,000
30,000
Please explain me this problem

Answer 1

The law says if you multiply the temperature by the wavelength, the answer will always be 30,000,000. The equation would be:
W*T=30,000,000
where T is temperature and W is wavelength (usually wavelength is the Greek letter Lambdoa, but I don't have Greek letters on my keyboard)
Using algebra you can rewrite this equation to say two other things:
W=30,000,000/T
or
T=30,000,000/W
The first problem tells you that T is 1,500, so W is 30,000,000/1,500 = 20,000.
The last problem says W is 30,000, so T is 30,000,000/30,000 = 1,000.
You do the rest.
