Final answer:
The electromagnetic spectrum ranges from long-wavelength radio waves to short-wavelength gamma rays, with the visible spectrum in the middle. The order of colors from shortest to longest wavelength is blue, yellow, red, and from lowest to highest frequency is red, yellow, blue. Understanding the relationship between wavelength and frequency is key.
Step-by-step explanation:
Understanding the Electromagnetic Spectrum
The electromagnetic spectrum encompasses all types of electromagnetic radiation, which differ from one another in terms of wavelength and frequency. When assembling the spectrum on a wavelength scale, it's important to place each type of radiation in the correct position. The spectrum ranges from long-wavelength, low-frequency radio waves to short-wavelength, high-frequency gamma rays.
The visible spectrum is a small part of the electromagnetic spectrum, which includes light that is visible to the human eye and ranges in wavelength from about 400 to 700 nanometers. In terms of colors, red light has the longest wavelength and blue light has a shorter wavelength, with yellow light falling in-between. Similarly, blue light has the highest frequency, while red light has the lowest frequency, with yellow again in-between these two extremes.
When placing colors of light in order according to wavelength and frequency, remember that the higher the frequency of the light wave, the shorter its wavelength. Therefore, for Part A, the order from shortest to longest wavelength would be blue, yellow, then red. For Part B, the order from lowest to highest frequency would be red, yellow, then blue.
Key Points About Electromagnetic Waves
- Higher frequency corresponds to shorter wavelength.
- Electromagnetic waves are produced in different ways across the spectrum.
- The spectrum is divided into multiple bands such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
