Label each of the following statements as true or false. a. Visible light is a form of electromagnetic radiation.

Verified step by step guidance

Understand the concept of electromagnetic radiation: Electromagnetic radiation is a form of energy that is propagated through space as a combination of electric and magnetic fields. It includes a wide range of wavelengths and frequencies.

Identify the electromagnetic spectrum: The electromagnetic spectrum encompasses all types of electromagnetic radiation, ranging from gamma rays with very short wavelengths to radio waves with very long wavelengths.

Locate visible light on the electromagnetic spectrum: Visible light is the portion of the electromagnetic spectrum that is detectable by the human eye. It falls between ultraviolet (UV) light and infrared (IR) light, with wavelengths approximately from 400 nm to 700 nm.

Determine the nature of visible light: Since visible light is part of the electromagnetic spectrum, it is indeed a form of electromagnetic radiation.

Conclude the statement: Based on the understanding that visible light is part of the electromagnetic spectrum, the statement 'Visible light is a form of electromagnetic radiation' is true.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Electromagnetic Radiation

Electromagnetic radiation is a form of energy that travels through space at the speed of light. It encompasses a spectrum of waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of electromagnetic radiation has different wavelengths and frequencies, which determine its properties and interactions with matter.

Visible Light

Visible light is the portion of the electromagnetic spectrum that is detectable by the human eye, typically ranging from wavelengths of about 400 to 700 nanometers. It is composed of various colors, which can be seen when light is refracted through a prism. Visible light plays a crucial role in photosynthesis and is essential for vision in many organisms.

True or False Statements

True or false statements are assertions that can be evaluated for their accuracy. In scientific contexts, these statements often relate to established facts or theories. Understanding the basis for labeling a statement as true or false requires knowledge of the underlying principles, such as the nature of electromagnetic radiation in this case.
