Question

Arrange the different types of electromagnetic radiation by wavelength. Only include the items that are forms of electromagnetic radiation. longest wavelength shortest wavelength Answer Bank high frequency ultraviolet radiation a red photon a low pitch sound wave green light low frequency ultraviolet radiation an X-ray photon

Answer 1

A lower frequency sound has a lower pitch which has Frequencies from 20 to 20 000 Hz are audible to the human ear. Thus frequency is 20 or 20 000 Hz OR/s Therefore wave length = 14989622.9 m - 14989.6229 m There are mainly 7 types of radiation preened in an electromagnetic spectrum. The wavelength and name of these radiations are as follows: Longest Wavelength a low pitch sound wave 14989622.9 m- 14989.6229 m ISI. A red photon 680-720 nm green photon 520 - 560 nm low frequency ultraviolet radiation 400 nm. high frequency ultraviolet radiation 10 nm an x-ray photon 10-10- 10-12 m shortest Wavelength Jau AWN Name of radiation Gamma X-rays Ultra violet Visible Infrared Micro wave Radio wave Wavelength < 10-12 m 10-10-10-12 m 3.0 x10-7-10-10 m 8.0 x10-7-4.0 x10-7 m 10-3-10-6 m 1.0-10'm >1.0 m Wavelength of any wave is the distance between consecutive peaks or troughs. It is denoted by a. The unit of wavelength is meter, cm, nm, mm etc. Frequency of any wave is the number of oscillations per second means the number of oscillation in one second. It is denoted by v. The unit of frequency is per second. Its SI unit is Hz , which is equal to s?. The energy of a photon is calculated by the Plank's equation. The equation is following: Erhv Here, E=Energy of photon, h=Plank's constant (6.626x 10 J:s), v=Frequency
