Question

If a soucre is trasnmitting electromagnetic wave of frequnecy 8.2 * 10^6hz tehn wavelength of teh electromagntic eave length trasnsmitted from the spouce will be

Answer 1

To find wavelength ( λ ), the equation is manipulated so that λ=cν . What is the wavelength of a electromagnetic wave that has a frequency of 4.95×1014 Hz ? Once you have frequency, you can use the first equation c=λ⋅ν to find the wavelength.

This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.

Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz.
