The peak intensity of radiation from Star Beta is 350 nm. What is the average surface temperature of Star Beta rounded to the nearest whole number? 121 K 6,547 K 8,285 K 10,348 K
Wien's Displacement Law is:
peak x surface temperature = 2.898 x 10^-3 m K
So,
surface temperature = 2.898 x 10^-3 m K / peak = 2.898 x 10^-3 m K / 350 x 10 -9 m
surface temperature = 8280 K
The closest to the choices is 8285 K.
