Arrange Ultraviolet rays, Violet rays, Yellow light, and Microwaves from highest to lowest frequency based on the electromagnetic spectrum order.
Question
Answer
This is a problem about ordering different types of electromagnetic radiation based on their frequency, from highest to lowest.
Step 1: Recall the general order of the electromagnetic spectrum.
The electromagnetic spectrum, ordered from lowest frequency (and longest wavelength) to highest frequency (and shortest wavelength), is typically:
The electromagnetic spectrum, ordered from lowest frequency (and longest wavelength) to highest frequency (and shortest wavelength), is typically:
Radio waves
Step 2: Identify the frequencies of the given types of radiation.
The types of radiation given are:
The types of radiation given are:
- Microwaves
- Yellow light (part of Visible Light)
- Violet rays (part of Visible Light)
- Ultraviolet (UV) rays
Step 3: Place the visible light components in order.
Visible light follows the order of colors based on frequency (from lowest to highest):
Red
Therefore, Violet light has a higher frequency than Yellow light.
Visible light follows the order of colors based on frequency (from lowest to highest):
Red
Therefore, Violet light has a higher frequency than Yellow light.
Step 4: Integrate all the given types into the full spectrum order (from lowest frequency to highest frequency):
Microwaves
Microwaves
Step 5: Arrange the list from highest frequency to lowest frequency.
We need to reverse the order found in Step 4:
We need to reverse the order found in Step 4:
Highest Frequency
Ultraviolet (UV) rays
The final arrangement is:
Ultraviolet (UV) rays, Violet rays, Yellow light, Microwaves.
Ultraviolet (UV) rays, Violet rays, Yellow light, Microwaves.
Theorems
• Relationship Between Frequency and Wavelength
For electromagnetic radiation traveling in a vacuum, the speed of light (
• Electromagnetic Spectrum Order by Frequency
The electromagnetic spectrum is ordered by increasing frequency (and decreasing wavelength). The general order relevant to this problem, from lowest frequency to highest frequency, is: Radio Waves < Microwaves < Infrared < Visible Light (Red
