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.
Write the following radiations in ascending order in respect of their frequencies: X-rays, microwaves, UV rays and radio waves.
The ascending order of frequencies for the given radiations is: Radio waves < Microwaves < UV rays < X-rays. Radio waves have the lowest frequencies, while X-rays have the highest frequencies among these radiations, indicating higher energy and shorter wavelengths. For more visit here: httpRead more

Illustrate by giving suitable examples, how you can show that electromagnetic waves carry both energy and momentum.
Electromagnetic waves carry energy and momentum, shown by: Solar panels: Convert sunlight (energy) into electricity. Radiation pressure: Light exerts pressure on objects, e.g., a light sail in space, propelling spacecraft. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/pRead more

The speed of an electromagnetic wave in a material medium is given by v = 1/√µɛ , µ being the permeability of the medium and ɛ its permittivity. How does its frequency change?
The frequency of an electromagnetic wave does not change in a material medium, as it depends solely on the source. However, the wave's speed and wavelength decrease due to the medium's permeability (µ) and permittivity (ɛ). For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/Read more

Which part of electromagnetic spectrum is absorbed from sunlight by ozone layae?
The ultraviolet (UV) radiation from sunlight, specifically UV-B (280–315 nm) and UV-C (100–280 nm), is absorbed by the ozone layer. This absorption protects life on Earth by reducing harmful radiation reaching the surface. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/pRead more

Do electromagnetic waves carry energy and momentum?
Yes, electromagnetic waves carry both energy and momentum. They transfer energy through their electric and magnetic fields and exert pressure (radiation pressure) when interacting with matter, demonstrating their momentum-carrying capability.
