Worked Solution & Example Answer:Figure 1 shows the parts of the electromagnetic spectrum? Which row of the table names the parts J, K and L of the electromagnetic spectrum? A B C D All electromagnetic waves can travel in a vacuum - Edexcel - GCSE Physics - Question 2 - 2021 - Paper 1
Step 1
Which row of the table names the parts J, K and L of the electromagnetic spectrum?
Answer
To identify the correct row for parts J, K, and L from the electromagnetic spectrum, we need to recall the order of the electromagnetic spectrum. The correct row should indicate the appropriate arrangement of wavelengths or frequency. In this case, the answer is:
C
- J: ultraviolet
- K: infrared
- L: radio
This corresponds to the portions of the electromagnetic spectrum shown in Figure 1.
Step 2
Which of these is the same for all electromagnetic waves travelling in a vacuum?
Answer
In the context of electromagnetic waves traveling in a vacuum, the following statement is true:
- All electromagnetic waves have the same amplitude in a vacuum, though the amplitude can vary based on the source and distance from it.
