Question

a veterinarian thinks that a dog has swallowed a key ring. which types of electromagnetic waves is the doctor most likely to use to check the dog?
gamma rays
microwaves
radio waves
x - rays

Explanation:

X - rays are commonly used in medical (including veterinary) imaging to view internal structures and foreign objects within the body as they can penetrate soft tissues and create an image of denser objects like a key - ring. Gamma rays are too harmful for routine diagnostic use, microwaves are mainly used for heating and communication, and radio waves are used in MRI (not for visualizing small foreign objects like a key - ring in this context).

Answer:

D. X - rays
