FLASHCARD QUESTION

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

FLASHCARD QUESTION

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

4.

FLASHCARD QUESTION

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa. This relationship is described by the equation: speed = wavelength × frequency.

FLASHCARD QUESTION

Front

What type of electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

6.

FLASHCARD QUESTION

Front

What type of electromagnetic wave has the highest frequency?

Back

Gamma rays have the highest frequency in the electromagnetic spectrum.

7.

FLASHCARD QUESTION

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from wavelengths of about 400 nm (violet) to 700 nm (red).
