Question

A wave has wavelength $50A^o$. Which of the following is a use of this wave?

• A. in detection of fracture in bones.
• B. in detection of planets
• C. in detection of water
• D. in detection of air

Answer 1

The correct option is A in detection of fracture in bones.

X-rays has a wavelength of $50\mathring{A}$.
X-rays are used by doctors to see inside people. The machines are managed by a trained x-ray technician. They pass easily through soft tissues, but not so easily through bones.
Hence, they help in detecting fractures in bones.
