Question

1. What is the peak wavelength emitted by a star with a surface temperature of 7070 K? Give your answer in nm (1 nm = 10^-9 m), but enter only the numerical part in the box.

2. By how much would a star's temperature need to increase in order for its peak wavelength to decrease from 460 to 360 nm? Your answer will be the change in temperature. Give your answer in K, but enter only the numerical part in the box.

3. By what factor would a star's radiated power per square meter of surface area increase as a result of its temperature increasing such that its peak wavelength emitted at its surface went from 510 to 360 nm? Your answer will be unitless (it's a ratio).
