What is the electromagnetic spectrum?

Back

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

Who proposed the wave-particle duality of electrons?

Back

Louis de Broglie proposed that electrons exhibit both wave-like and particle-like properties.

Front

What is ionizing radiation?

Back

Ionizing radiation is a type of radiation that carries enough energy to ionize atoms or molecules, which can lead to health effects such as cancer.

Front

What unit is used to measure frequency in the International System of Units (SI)?

Back

Frequency is measured in hertz (Hz) in the SI system.

Front

Who formulated the wave equation for electrons?

Back

Erwin Schrodinger formulated the wave equation that describes the behavior of electrons in an atom.

Front

What is the order of colors in the visible spectrum from lowest to highest frequency?

Back

The order of colors in the visible spectrum from lowest to highest frequency is red, orange, yellow, green, blue, and violet.

Front

What is non-ionizing radiation?

Back

Non-ionizing radiation is a type of electromagnetic radiation that does not carry enough energy to ionize atoms or molecules, such as radio waves and microwaves.

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.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

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 about 400 nm (violet) to 700 nm (red).
