<h2>Further Explanation
</h2><h3>A wave
</h3>
- A wave is a transmission of a disturbance. It involves transmission of energy from one point which is the source to another point.
- Waves may be classified depending on the need for a transmission medium or based on the vibration of particles relative to the direction of wave motion.
- Waves may be either transverse or longitudinal based on the direction of wave motion relative to the vibration of particles
- Additionally waves may be classified as either electromagnetic wave or mechanical based on the need for a transmission medium.
<h3>Electromagnetic waves </h3>
- Electromagnetic waves are types of waves that do not require a material medium for transmission.
- All waves of the electromagnetic spectrum are electromagnetic transverse waves that do not require a material medium for transmission.
- They include; radio waves, microwaves, infrared, visible light, ultra-violet, x-rays, and gamma rays.
- All waves of the electromagnetic spectrum travel with a speed of light, 3.0 x10^8 m/s.
Therefore, the speed of microwave is 3.0 x 10^8 m/s
<h3>Relationship between velocity, frequency, and wavelength of a wave.
</h3>
- Velocity, frequency and wavelength are related such that;
- Velocity = frequency x wavelength
c = f x λ
Therefore; to get frequency;
f = c/λ
c = 3.0 x 10^8 m/s
λ = 3.52 mm or 3.52 x 10^-3 m
Thus;
f = (3.0 x 10^8 m/s)/(3.52 x 10^-3 m)
= 8.522 x 10^10 Hz
Therefore, the frequency of a microwave with a wavelength of 3.52 mm is 8.522 x 10^10 Hz .
