To solve this problem, we need to arrange the types of electromagnetic radiation in order based on their frequency. The diagram shows waves that start with long wavelengths (low frequency) on the left and get shorter and shorter (high frequency) as they move to the right.
Here is the step-by-step logic:
1.
Understand the Relationship: Frequency and wavelength are opposites.
*
Low Frequency = Long Wavelength (The waves are stretched out). This is on the
left side of your chart.
*
High Frequency = Short Wavelength (The waves are squished together). This is on the
right side of your chart.
2.
Identify the Order: We need to list the electromagnetic spectrum from lowest energy/frequency to highest energy/frequency. A common way to remember this is the acronym
"RLMIVUX" (Radio, Light/Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma). *Note: Microwaves are often grouped near Radio or Infrared depending on the specific chart, but usually go between Radio and Infrared.*
3.
Fill in the Boxes (Left to Right):
*
Box 1 (Far Left - Lowest Frequency/Longest Wave): Radio Waves. These have the longest wavelengths and lowest energy.
*
Box 2: Microwaves. These have slightly higher frequency than radio waves.
*
Box 3: Infrared. You feel this as heat. It has higher frequency than microwaves.
*
Box 4: Visible Light. This is the only part we can see (Rainbow colors: Red, Orange, Yellow, Green, Blue, Indigo, Violet). Red is on the lower frequency side, Violet on the higher.
*
Box 5: Ultraviolet (UV). This comes from the sun and can give you a sunburn. It has higher frequency than visible light.
*
Box 6: X-Rays. These have very high frequency and can pass through soft tissue (used for bone pictures).
*
Box 7 (Far Right - Highest Frequency/Shortest Wave): Gamma Rays. These have the shortest wavelength and highest energy.
4.
Speed and Size Rows:
*
Speed: All electromagnetic waves travel at the same speed in a vacuum (the speed of light). So, you would write "Same" or "$c$" (or $3 \times 10^8$ m/s) in every box for Speed.
*
Size (Wavelength): Since the chart asks to arrange by frequency, the "Size" row corresponds to the wavelength. It goes from
Largest on the left to
Smallest on the right.
Final Answer:
Here is the correct order to fill in the boxes from
Left to Right:
| Box 1 | Box 2 | Box 3 | Box 4 | Box 5 | Box 6 | Box 7 |
| :--- | :--- | :--- | :--- | :--- | :--- | :--- |
|
Radio Waves |
Microwaves |
Infrared |
Visible Light |
Ultraviolet |
X-Rays |
Gamma Rays |
*(Note: For the "Speed" row, the answer is the
same for all columns. For the "Size/Wavelength" row, it decreases from Largest on the left to Smallest on the right.)*
