When used in physical therapy, a diathermy machine gives the sensation of "deep heat" in the tissue being treated.
If a diathermy machine creates electromagnetic radiation with a frequency of 27 MHz, what type of electromagnetic radiation is it creating?
| a)Radio waves |
| b) Visible light |
| c) Infrared radiation |
| d)Microwave radiation |
Homework Answers
for electro magnetic radiation
wavelength =c/f
=3*10^8/(27*10^6)
=11.11 m
so.option (a) is correct....Radiowaves.

Radio waves and microwaves are used in therapy to provide "deep heating" of tissue because the waves penetrate beneath the surface of the body and deposit energy. We define the penetration depth as the depth at which the wave intensity has decreased to 37% of its value at the surface. The penetration depth is 15 cm for27 MHz radio waves. For radio frequencies such as this, the penetration depth is proportional to λ−−√, the square root of the wavelength. What...

Learning Goal: To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol A (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given...

PLEASE ANSWERS TO ALL QUESTIONS NEEDED, THANKS Problem 13.10(a) Purpose: This is to help familiarize you with characteristics of electromagnetic waves. Problem: An electromagnetic wave travels in the z direction. The electric field in the wave is given by the expression E(z,t) = E0cos(kz-ωt)y. (Bold letter are vectors.) At z = 0 and t = 0, in what direction does the magnetic field point? Hints: Remember that E crossed into B gives the direction of travel. Enter your answer,...
