Label each of the following statements as true or false. b. Ultraviolet light has longer wavelengths than visible light.

Verified step by step guidance

1. Understand the electromagnetic spectrum, which includes different types of electromagnetic radiation arranged by wavelength.
2. Recall that ultraviolet (UV) light and visible light are both part of the electromagnetic spectrum.
3. Know that the electromagnetic spectrum is arranged from longer wavelengths to shorter wavelengths: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
4. Recognize that visible light has wavelengths ranging approximately from 400 nm (violet) to 700 nm (red).
5. Identify that ultraviolet light has shorter wavelengths than visible light, typically ranging from about 10 nm to 400 nm.

Key Concepts

Electromagnetic Spectrum

The electromagnetic spectrum encompasses all types of electromagnetic radiation, arranged by wavelength. It includes gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves. Understanding the spectrum is crucial for distinguishing between different types of light and their properties.

Wavelength and Frequency

Wavelength is the distance between successive peaks of a wave, while frequency is the number of waves that pass a point in one second. These two properties are inversely related; as wavelength increases, frequency decreases. This relationship is fundamental in understanding the characteristics of different types of light.

Visible Light Range

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye, typically ranging from about 400 nm (violet) to 700 nm (red). Ultraviolet light, which lies just beyond the visible spectrum, has shorter wavelengths (10 nm to 400 nm) than visible light, making the statement in the question false.
