Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

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

Front

What happens to frequency as wavelength increases?

Back

As wavelength increases, frequency decreases.

Front

What type of electromagnetic wave has the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

Front

What type of electromagnetic wave has the lowest energy?

Back

Microwaves have the lowest energy among the options provided.

Front

True or False: Electromagnetic waves can travel through a vacuum.

Back

True.

Front

What is the relationship between wavelength and energy in electromagnetic waves?

Back

Longer wavelengths correspond to lower energy, while shorter wavelengths correspond to higher energy.

Front

What type of electromagnetic radiation is used in microwave ovens?

Back

Microwaves are used in microwave ovens.

Front

What is the frequency of a wave with a wavelength of 1 meter? (Use the speed of light, c = 3 x 10^8 m/s)

Back

Frequency (f) = Speed of light (c) / Wavelength (λ) = 3 x 10^8 m/s / 1 m = 3 x 10^8 Hz.

Front

What is visible light?

Back

Visible light 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).

Front

What are quasars?

Back

Quasars are extremely distant celestial objects that emit large amounts of energy, often observed in the form of electromagnetic radiation.
