Question
Which of the following has shortest wavelength?
- Infrared radiation
- X-rays
- UV rays
- Gamma rays
Hint:
These rays are used to
- Sterilize medical equipment.
- Sterilize food
- Used as tracers in medicine.
The correct answer is: Gamma rays
- Frequency and energy is inversely proportional to wavelength.
- Gamma rays has highest frequency and energy but shortest wavelength.
- So, the correct option is d.
