NEETPhysicsElectromagnetic Waves
Which of the following represents the typical wavelength range of the electromagnetic wave that is widely used for studying crystal structures?
Options
- A10⁻⁸ m to 10⁻¹³ m
- B4 10⁻⁷ m to 6 10⁻¹⁰ m
- C10⁻³ m to 7 10⁻⁷ m
- D0.3 m to 10⁻³ m
Correct answer
A. 10⁻⁸ m to 10⁻¹³ m
Step-by-step solution
The electromagnetic waves used for studying crystal structures are X-rays. According to the electromagnetic spectrum, X-rays have a typical wavelength range from about 10⁻⁸ m (10 nm) down to 10⁻¹³ m ( 10⁻⁴ nm). The range 4 10⁻⁷ m to 6 10⁻¹⁰ m corresponds to ultraviolet rays. The range 10⁻³ m to 7 10⁻⁷ m corresponds to infrared waves. The range 0.3 m to 10⁻³ m corresponds to microwaves. Answer: 10⁻⁸ m to 10⁻¹³ m
