Understand that all electromagnetic waves are transverse and propagate at a uniform speed within a vacuum.
Explain, using relevant examples, how all electromagnetic waves transfer energy from a source to an observer.
Investigate refraction in rectangular glass blocks to understand the interaction of electromagnetic waves with physical matter.
Recall the primary groupings of the continuous electromagnetic spectrum in sequential order: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Describe the electromagnetic spectrum as a continuous range, organizing radiations in order of decreasing wavelength and correspondingly increasing frequency.
Understand that the human eye is only capable of detecting a highly restricted range of frequencies within the electromagnetic spectrum.
Explain that the absorption, transmission, refraction, and reflection of electromagnetic waves by different substances vary according to the specific wavelength.
Analyze the physical effects caused by differences in the velocities of electromagnetic waves as they travel through various substances.
