Question

of the visible spectrum, which color has the lowest frequency (and therefore lowest energy)?
o a red light
o b yellow light
o c violet light
o d green light
question 22 (2 points)

1. which category is our sun located in?

o a white dwarfs
o b main sequence
o c supergiants
o d giants

Explanation:

• For the first question:
• According to the properties of the visible spectrum, the frequency of light is inversely related to its wavelength. Red light has the longest wavelength among the given options (red, yellow, violet, green). Using the formula \(E = h

u\) (where \(E\) is energy, \(h\) is Planck's constant, and \(
u\) is frequency), since energy is directly proportional to frequency, the light with the lowest frequency (red) has the lowest energy.

• For the second question:
• The Sun is currently in the Main - Sequence stage of its stellar evolution. Main - sequence stars, like the Sun, are in a stable phase where they fuse hydrogen into helium in their cores. White Dwarfs are the remnants of low - mass stars (like the Sun will become after its red - giant phase). Supergiants are very large and luminous stars that have evolved off the main sequence. Giants are also evolved stars that have expanded from their main - sequence size.

Answer:

• First question: A. red light
• Second question: B. Main Sequence
