longitudinal wave- bask and forth in the direction of the motion of the motion of the wave.

electromagnetic wave- two alternating waves moving at right angles to each other.

Explanation:

In a longitudinal wave, the particles vibrate at right angles in reference to the wave motion.

In a transverse wave, the particles vibrate parallel to the wave motion

A microwave oven operates at 2.00 ghz . what is the wavelength of the radiation produced by this appliance? express the waveleng
yan [13]
<span>Since frequency and wavelength have inverse relationship. It can be expressed by the equation: ν.λ = c Where, v = frequency of the electromagnetic wave. λ = it's wavelength c = the speed of light in a vacuum. v = 2.00 Ghz x 10^9 Hz / 1 Ghz = 2.00 x 10^9 Hz that means that in one second it covers 2.00 x 10^9 cycles. λ = 3.10^8 m/s / 2.00 x 10^9 /s = 1.25E-10 nanometers</span>
