What is the wavelength of a radio wave of frequency 89 MHz?

Typical radio wave frequencies are about 88~108 MHz. The wavelength is thus typically about 3.41×109 ~ 2.78×109 nm.

What is the wavelength of a radio station emitting its signal at 95.5 MHz?

The wavelength of a radio signal at 95.5 MHz is about 1 m long, or 10 m.

What is the wavelength of FM radio waves?

Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz.

What is the wavelength of a radio wave of frequency 1mhz?

A 1 megahertz radio wave (mid-AM band) has a wavelength of 299.79 meters (983.6 ft).

What is the frequency of radio waves with wavelength of 20 m?


What is the formula to calculate frequency?

The formula for frequency is: f ( frequency ) = 1 / T (period). f = c / λ = wave speed c (m/s) / wavelength λ (m).

What is the relationship between frequency and wavelength?

The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

What is the wavelength of 1 Hz?

Wavelength of a sound in air at 1 Hz: 340 m A: These molecules already react to the inward motion of the loudspeaker membrane, moving towards the source.

Which wave has lowest frequency?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

Which is the correct formula for finding the frequency of an electromagnetic wave?

Calculating Wave Frequency or Wavelength from Wave Speed For example, suppose that a wave is traveling at a speed of 2 meters per second and has a wavelength of 1 meter. Then the frequency of the wave is: Frequency = 2m/s1m=2 waves /s, or 2 Hz.

What kinds of waves have the shortest wavelength?

Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

Is AM or FM stronger?

With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static.

Which has longer wavelength AM or FM?

AM broadcasts use longer wavelength radio waves than FM broadcasts. Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere. In FM broadcasts, sound signals are encoded by changing the frequency of radio waves.

What is the frequency of a radio wave?

radio waves: Designates a portion of the electromagnetic spectrum having frequencies ranging from 300 GHz to 3 kHz, or equivalently, wavelengths from 1 millimeter to 100 kilometers.
