Question

question 4 of 19 > use the provided chart to answer the question. consult the electromagnetic spectrum as needed. a star with which of the blackbody spectra emits the highest proportion of its light in the orange part of the spectrum? star a star c star b all of these stars emit the highest proportion of light in the orange part of the spectrum.

Explanation:

Step1: Identify orange - wavelength range

The orange part of the visible spectrum is approximately 590 - 625 nm.

Step2: Check peak wavelengths of stars

From the graph, star A has its peak around 500 nm (blue - green region), star B has its peak around 700 nm (red region), and star C has its peak around 1000 nm (infra - red region). None of them have their peak in the orange part of the spectrum. But if we consider the relative distribution, we need to see which star has more of its light in the orange range. Since the graph is not detailed enough to calculate exact proportions, we assume that the star whose peak is closest to the orange range will have the highest proportion in the orange part. Star B's peak is closest to the orange range among the three.

Answer:

C. star B
