Ans:it would become more dense

Ques:Shorter wavelengths (higher frequencies) correspond to higher energies and thus hotter star temperatures. Would a star that is significantly cooler than the sun, which is outputting blue light which is higher in frequency that the yellow light of the Sun, be hotter or colder??

Ans:colder?

Ques:Because all electromagnetic waves travel at the same speed through space, a wave with a shorter wavelength must have a higher frequency, and vice versa. If Jim is projecting electromagnetic waves out into space and he increases the size of the wavelength being transmitted, what happens to the frequency of that wavelength decreases or increases?

Ans:decreases
