Question

light of any kind: (select all that apply).
originate from the accelerated of motion of electrons.
travels at a speed of 300,000,000 m/s.
is an electromagnetic wave.
is a tiny part of the electromagnetic spectrum.
is energy carried in waves of electric and magnetic fields that continually regenerate each other.

Explanation:

• Light is an electromagnetic wave. Electromagnetic waves are generated by the accelerated motion of electrons. Light (as part of the electromagnetic spectrum) travels at \(c = 3\times10^{8}\text{ m/s}=300000000\text{ m/s}\). Electromagnetic waves consist of oscillating electric and magnetic fields that regenerate each other.
• The visible light (a common type of light we refer to) is a tiny part of the entire electromagnetic spectrum. But when we say "light of any kind" in the context of electromagnetic waves (which is a broad category including radio waves, microwaves, infrared, visible light, ultraviolet, X - rays, and gamma rays), the statement "Is a tiny part of the electromagnetic spectrum" is incorrect for the entire category of light (electromagnetic waves).

Answer:

• Originates from the accelerated of motion of electrons.
• Travels at a speed of \(300,000,000\text{ m/s}\).
• Is an electromagnetic wave.
• Is energy carried in waves of electric and magnetic fields that continually regenerate each other.
