Question 25

Visible light is a part of the electromagnetic spectrum that can be detected by the human eye. The visible spectrum includes colors like red, orange, yellow, green, blue, indigo, and violet. Blue light is within this visible range. Gamma rays, ultraviolet, and infrared are outside the visible light range. Gamma rays have very high energy and short wavelengths, ultraviolet has shorter wavelengths than visible light (not visible to the naked eye), and infrared has longer wavelengths than visible light (also not visible to the naked eye).

A white dwarf is a small, very dense star. It is typically the size of a planet. It forms when a low - mass star (like the Sun) has exhausted its central nuclear fuel (hydrogen and helium fusion in the core stops). The outer layers of the star are shed as a planetary nebula, and the core remains as a white dwarf. A black dwarf is a theoretical object that would be a cooled - down white dwarf, but no black dwarfs are thought to exist in the universe yet as the universe is not old enough for white dwarfs to cool completely. A super red giant is a very large star (much larger than a planet - sized object). Mass is a general property (amount of matter) and not a type of star as described in the question.

Answer:

a. blue light
