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
The correct answer is option C: J is ultraviolet, K is infrared, and L is radio. This corresponds to the conventional ordering of the electromagnetic spectrum, where ultraviolet lies between visible light and infrared.
Step 2
Which of these is the same for all electromagnetic waves travelling in a vacuum?
Answer
The same property for all electromagnetic waves travelling in a vacuum is their amplitude. Amplitude reflects the maximum displacement of the wave and is a common characteristic across different types of electromagnetic radiation.
