Correct answer: B
-
Recall the electromagnetic spectrum order
In increasing order of wavelength, electromagnetic waves are arranged as:
-
Pick only the waves mentioned in the options
The given types are:
- gamma-ray
- X-ray
- visible
- microwave
Therefore, their ascending order of wavelength is:
-
Compare with the options
- A: visible, X-ray, gamma-ray, microwave → not ascending
- B: gamma-ray, X-ray, visible, microwave → correct
- C: X-ray, gamma-ray, visible, microwave → first two are reversed
- D: microwave, visible, gamma-ray, X-ray → descending at first
-
Derived answer
The correct option is:
-
Comparison with stored correct answer
Stored correct answer = B
My derived answer = B
Hence, they agree.
