Recall that all electromagnetic waves are transverse waves that travel at the same velocity through a vacuum (space).
Explain, using practical examples, how electromagnetic waves transfer energy from a source to an absorber.
Identify visible light as a specific segment of the broader electromagnetic wave spectrum.
Describe the continuous electromagnetic spectrum, categorizing it from long wavelength to short wavelength (and low to high frequency): radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Understand that the human eye is only capable of detecting a limited range of these frequencies (visible light).
Provide examples of practical applications for each region of the electromagnetic spectrum, such as communications, cooking, medical imaging, and sterilization.
Recall and apply the mathematical relationship between frequency and wavelength across the entire electromagnetic spectrum.
Investigate practically how the absorption and emission of infrared radiation depend on the nature and color of different surfaces.
