Write your answer first. You can study the marking guidance whenever you need it.
Study the marking See what earns credit and compare it with a full-mark answer.
Marking points
- 1 Gives one distinct credited similarity other than transferring energy.
- 2 Gives a second distinct credited similarity.
- 3 Gives a third distinct credited similarity.
Full-mark answer
Both are electromagnetic waves; both are transverse waves; and both travel at the speed of light in a vacuum and can travel without a medium.
Why this answer loses marks
Both can be reflected, refracted and absorbed.
The official guidance ignores those statements here; use distinct credited properties shared across the electromagnetic spectrum.
