Use the claim to answer the question.
Claim: Electromagnetic radiation can be described by a wave model or a particle model, depending on the situation.
Is this a scientific claim?

A student states, "The wave model is better than the particle model for electromagnetic radiation because it is easier to understand." Is the student's statement a scientific claim?(1 point)
Responses
No, it isn't because the particle model is better than the wave model.
No, it isn't because the particle model is better than the wave model.
Yes, it is because there is ample proof that wave models are easier.

A physician is going to use high-frequency electromagnetic radiation to treat cancer in a patient. Which is a claim about this event?(1 point)
Responses
A wave model is most useful for describing the frequency of the radiation.
