What else can I help you with?
Does a wireless router broadcast or transmit radio waves when no computers are connected or does a router wait for a signal from the computers wireless adaptor before transmitting and radio waves?
It has to always be broadcasting radio waves otherwise no devices will ever find the router.
Why can radio telescopes be used 24 hrs a day?
they do not need visivle light to obtain images
What are some natural sources of radio waves?
We generally think of radio waves (radio electromagnetic radiation) as those frequencies of electromagnetic (EM) radiation that fall within a band of frequencies below those of light. These include microwave bands, on which satellites communicate and cell phone operate, as well as the familiar microwave oven. Radar also operates in this band. Below that we find television signals, as well as some two-way radio signals. Other forms of communications radio signals (like amateur or "ham" radio) as well as broadcast radio operate below the television bands. By considering the types of equipment mentioned above, it is possible to make a list of some sources of radio electromagnetic radiation.
Where does radio wave fit into the electromagnetic spectrum?
Here are the ways you use the radio portion of the electromagnetic spectrumjust while you're in your car :-- listen to the traffic and weather reports-- listen to music and news-- use your GPS to find an address-- get a call on your cellphone-- talk on your CB-- open the garage door without getting out of the car in the rain
Where in the electromagnetic spectrum would you find waves of wavelength 0.01metres?
Frequency = (speed) / (wavelength) = (3 x 108) / 10-2 = 3 x 1010 = 30 GHz.That portion of the radio spectrum is allocated for various satellite applications,radio astronomy, radio navigation, earth and space exploration.
To find the distances between two distant objects without the use of trigonometry?
It depends on the objects, how far apart they are and whether or not one can be seen from the other. If they are moderately far apart, echo location (sonar or radar) located at one of the objects can be used. A beam of radio or sound waves is aimed at the object and the time taken to receive an echo is measured. Since the speed of radio waves or sound waves in the relevant medium is known, the distance travelled by these waves can be calculated. The distance to the object is then half the calculated distance (the waves have to go there and come back).
What is the process of using reflected sound waves to find objects?
The process of using reflected sound waves to find objects is called echolocation. This involves emitting sound waves and then listening for the echoes as they bounce back off objects. By analyzing the time it takes for the echoes to return and the intensity of the sound waves, individuals or animals can determine the distance and location of objects.
Using refleced sound waves to find objects?
Whut?
What do radio telescopes use to gather and forces radio waves?
Radio telescopes use large antennas to gather radio waves by focusing them onto a receiver. The receiver amplifies and converts these radio waves into electrical signals that can be analyzed by scientists to study celestial objects and phenomena in space.
Does a wireless router broadcast or transmit radio waves when no computers are connected or does a router wait for a signal from the computers wireless adaptor before transmitting and radio waves?
It has to always be broadcasting radio waves otherwise no devices will ever find the router.
What is the name for the method used to find objects that are underwater?
Sonar, which stands for "sound navigation and ranging," is the method used to find objects underwater by emitting sound waves and measuring the time it takes for them to bounce back. This allows for the detection and location of underwater objects like shipwrecks, submarines, and marine life.
What is a method that uses sound waves to find objects underwater?
Sonar (Sound Navigation and Ranging) is a method that uses sound waves to find objects underwater. It works by emitting sound pulses and measuring the time it takes for the sound waves to bounce back, allowing for the detection of underwater objects such as submarines, ships, or marine life.
How do p and s waves provide the location of the earthquakes epicenter?
you have to find the s and p to find and then you have the awnser
Is the process of locating objects by bouncing sounds off them?
The process of locating objects by bouncing sound off them is called echolocation. Animals like bats and dolphins use this method to navigate and find prey in their environments. This technique involves emitting sound waves and listening for the echoes to determine the location, size, and shape of objects.
How sound waves can be used to find underwater objects?
Sound travels through water. Sound reflects from objects with different densities. You can listen for the echoes.
Where can one find a Radio Flyer Scooter?
Radio Flyer Scooters are available online at Amazon and at many retail outlets nationwide. Consumers can find the closes location to buy a Radio Flyer Scooter on the Radio Flyer website.
How radio waves detect signals from other parts of the universe?
they use telescopes that find certain wavelengths
