What is the wavelength of a radio signal broadcast at a frequency of 99.0 MHz?

Answer 1

#3.bar(03)m#

Radio signals are electromagnetic waves and these travel with the speed of light #c=3xx10^8ms^-1#.
The expression connecting speed, wavelength #lambda# and frequency #n# of electromagnetic waves is #c=nxxlambda#
Inserting given and known numbers #3xx10^8=99.0xx10^6xxlambda#, solving for wavelength #lambda=(3xx10^8)/(99.0xx10^6)=3.bar(03)m#

You can use the formula to calculate the wavelength (( \lambda )) of a wave:

[ \lambda = \frac{c}{f} ]

Where:

  • ( \lambda ) is the wavelength (in meters),
  • ( c ) is the speed of light in a vacuum (approximately ( 3 \times 10^8 ) meters per second),
  • ( f ) is the frequency of the wave (in hertz).

Given: ( f = 99.0 ) MHz (megahertz, which is ( 99.0 \times 10^6 ) hertz).

Plugging in the values: [ \lambda = \frac{3 \times 10^8}{99.0 \times 10^6} ]

[ \lambda ≈ 3.03 , \text{meters} ]

Therefore, the wavelength of the radio signal broadcast at a frequency of ( 99.0 ) MHz is approximately ( 3.03 ) meters.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
