What is the wavelength used by a radio station that broadcasts?

Radio Waves. Radio waves are EM (Electromagnetic)waves that have wavelengths between 1 millimeter and 100 kilometers (or 300 GHz and 3 kHz in frequency).

What is the wavelength of an electromagnetic wave that has a frequency of 1 Hz?

The wavelength of an electromagnetic wave that has a frequency of 1Hz is 3*10^8m.

What is the wavelength of the electromagnetic wave used by this phone?

The frequency at which non-ionizing radiation becomes ionizing is in the ultraviolet range, or somewhere below wavelengths of 10^-7 m. Cell phones use radio waves to communicate with cell towers, and these waves have wavelengths of approximately 10-1000 m, which are much too large to be ionizing.

What are long wave radio waves used for?

They are used in standard broadcast radio and television, shortwave radio, navigation and air-traffic control, cellular telephony, and even remote-controlled toys. (For a fuller treatment, see electromagnetic radiation: Radio waves.) Radio waves lie at the low-frequency end of the electromagnetic spectrum.

What is the wavelength of a radio station that broadcasts at 92.9 MHz?

The wavelength of a 92.9 MHz radio wave is 3.23 meters.

What is the wavelength of a sound wave with a frequency of 220 Hz?

Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium. Hence, the wavelength of the sound wave is 2 m.

What are the 7 wavelengths?

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

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 shortest wavelength?

Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

What is the most important electromagnetic wave?

The different types of waves have different uses and functions in our everyday lives. The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

How does frequency play a role in cell phones?

The base station responds to the cellular phone signal by assigning the phone an available radio frequency channel. When the RF channel is assigned, modulated radio signals are simultaneously received and transmitted, allowing voice information to be carried between the cell phone and the base.

What kind of waves do mobile phones use?

Mobile phones communicate by transmitting radio waves through a network of fixed antennas called base stations. Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body.

Who uses long wave radio?

In Europe, Africa, and large parts of Asia (International Telecommunication Union Region 1), where a range of frequencies between 148.5 and 283.5 kHz is used for AM broadcasting in addition to the medium- wave band, the term longwave usually refers specifically to this broadcasting band, which falls wholly within the

Do radio waves pass through the body?

Absolutely! Radio waves not only pass through the human body, but are also absorbed by them. In fact, strong enough radio waves can kill a person if they are strong enough!

How do we use visible waves in everyday life?

We concentrate visible light to make lasers to use in everything from surgery, to CD players to laser pointers. Visible light waves also make our TV, computer and cell phone screens work.
