Share & grow the world's knowledge!
We want to connect the people who have knowledge to the people who need it, to bring together people with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
How are infrared waves produced? What is the range of their wavelength?
Infrared waves are produced by the thermal motion of atoms and molecules in a heated object. Their wavelength ranges from 700 nm to 1 mm in the electromagnetic spectrum, lying just beyond visible red light.

How are radio waves produced?
Radio waves are produced by the oscillations of electric charges in a conducting antenna. These oscillations generate electromagnetic waves, which propagate through space and are used in communication systems like radios, televisions, and cell phones.

Welders wear special goggles or face masks with glass windows to protect their eyes from electromagnetic radiations. Name the radiations and write the range of their frequency.
Welders wear special goggles to protect their eyes from ultraviolet (UV) radiation and infrared (IR) radiation. UV radiation has a frequency range of 8 × 10¹⁴ to 3 × 10¹⁶ Hz, while IR radiation ranges from 3 × 10¹¹ to 4 × 10¹⁴ Hz, both of which can harm the eyes. For more visit here: https://www.tiwRead more

Name the e.m. waves used for studying crystal structure of solids. What is its frequency range?
X-rays are used for studying the crystal structure of solids through X-ray diffraction. Their frequency range is approximately 3 × 10¹⁶ to 3 × 10²⁰ Hz, corresponding to wavelengths between 0.01 to 10 nanometers.

Name the part of electromagnetic spectrum whose wavelenght lies in the range of 10-¹⁰ m. Give its one use.
The part of the electromagnetic spectrum with a wavelength of 10⁻¹⁰ m falls under X-rays. One use of X-rays is in medical imaging, where they help in creating images of the inside of the body for diagnosis.
