b) Radioisotope technique requires injections.
c) Bone is imaged better by X-rays than by the radioisotope technique.

c) Wavelength can change appreciably and it will increase in less dense media.
d) Velocity can change appreciably and it will decrease in denser media.
e) None of (a) through (d) is correct answer
Explanation / Answer
Answer 1:- option (c) is right.
bone is imaged better by X-RAY than by the radioisotope technique.
Answer 2:- Option (a) is right.
because when light travel from one medium to another medium then only velocity and wavelength changes. Frequency does not change.
