Question

1. choose the best answer.

what is the electromagnetic spectrum?
the range of different types of electromagnetic radiation
the pattern observed when light passes through a prism and is separated by frequencies
the pattern observed when light passes through a prism and is separated by wavelengths
the range of electromagnetic waves according to matter and energy

1. choose the best answer.

what is an emission spectrum?
the distribution of all electromagnetic waves according to wavelength and frequency
the distribution of electromagnetic waves according to matter and energy
the pattern observed when light passes through a prism and is separated by amplitudes
the pattern observed when light passes through a prism and is separated by frequencies

Explanation:

• The electromagnetic spectrum is defined as the range of different types of electromagnetic radiation. Electromagnetic radiation includes various forms like radio waves, microwaves, infrared, visible light, ultraviolet, X - rays, and gamma rays.
• An emission spectrum is the pattern observed when light passes through a prism and is separated by frequencies. When atoms or molecules emit light, they do so at specific frequencies which can be separated and observed as distinct lines or bands in an emission spectrum.

Answer:

1. the range of different types of electromagnetic radiation
2. the pattern observed when light passes through a prism and is separated by frequencies
