Question 16 (1 point)

What does Wien's Law allow us to do?

Question 16 options:

a)

Measure the chemical content of a planet

b)

Determine the distance to a star

c)

Determine the surface temperature of a star

d)

Determine the luminosity of the star

Answer 1

c) Determine the surface temperature of a star

Step-by-step explanation:

Wien's Law:

It states that for a black body wavelength is inverse proportional to the temperature or we can say that temperature is inverse proportional to the wavelength.

Form Wien's Law

`\lambda =(2.88)/(T)\ mm`

Where T is the temperature in Kelvin

λ is the wavelength.

So by measuring the wavelength we can find the temperature of star by using Wein's law.

So our option C is correct,..
