Radio waves can travel long distances due to their long wavelengths. These wavelengths allow them to diffract around obstacles and follow the curvature of the Earth, resulting in effective transmission over vast areas. This property makes radio waves ideal for communication technologies, such as broadcasting and satellite signals.

What do long radio waves use?
Long radio waves, typically in the frequency range of 30 kHz to 300 kHz, use large antennas for transmission and reception due to their long wavelength. These waves are often utilized in AM broadcasting, maritime communication, and navigation systems. Their ability to diffract around obstacles and travel long distances makes them particularly effective for reaching remote areas. Additionally, long radio waves can penetrate through the ionosphere, allowing for communication beyond the horizon.
WHAT frequency sounds are detectable at longer ranges in seawater?
Low frequency sounds (20-1,000 Hz) can travel long distances in seawater due to their ability to penetrate further and experience less attenuation compared to higher frequency sounds. This makes them detectable over greater distances in the ocean.
Can a bullet shot farther west than east because of the earths rotation?
Bullets cannot be shot farther west or east due to the Earth's rotation, as their trajectory is primarily determined by the force and direction of the shot. The rotation of the Earth only impacts large distances and long travel times, not the trajectory of a bullet over short distances.
What increases when sound wave travel in solid from gas medium frequency or wavelength?
Velocity increases when sound waves travel from gas medium to solid medium. As velocity = frequency * wave length and the frequency does not change, v is directly proportional to the wave length... Hence the wavelength increases.
Why do substances travel different distances in chromatography?
Due to the fact that different substances possess different retention time (they do differ from their size,shalpe,mol wt etc.)
What type of wave has the longest wavelength and the lowest frequency?
The type of wave that has the longest wavelength and lowest frequency is a radio wave. These waves are used for communication and broadcasting due to their ability to travel long distances.
Can for ultrasound wave travel long distance in air?
No, ultrasound waves cannot travel long distances in air due to the high attenuation of the waves caused by air. The waves lose energy quickly as they travel through air, limiting the distance they can travel effectively. Additionally, scattering and absorption of ultrasound waves in air further reduce their ability to propagate over long distances.
What is 1550nm?
1550 nm refers to a wavelength of light in the infrared spectrum, commonly used in optical fiber communication. This wavelength is significant because it offers low attenuation and minimal dispersion, allowing signals to travel long distances without significant loss of quality. Additionally, 1550 nm is well-suited for fiber optic systems due to its compatibility with erbium-doped fiber amplifiers (EDFAs), which can amplify signals effectively at this wavelength.
Why is wave with longer wavelength able to travel further?
Waves with longer wavelengths are able to travel further because they carry more energy due to their longer period, which allows them to maintain their intensity over greater distances. Additionally, longer wavelengths are less affected by obstacles and can diffract around barriers more easily, enabling them to travel longer distances without losing their strength.
Does AM radio travel through the ionosphere?
Any Amplitude Modulated radio signal will penetrate the ionosphere if its carrier frequency is high enough. Signals in the commercial AM broadcast band, with frequencies between 530 and 1700 KHz, aren't high enough. Most of their energy reflects from the ionosphere.
How far can sound travel before it dies out?
Sound can travel long distances, but it eventually dies out due to factors like air resistance and absorption. In general, sound can travel up to several miles before becoming too faint to hear.
What is the relationship between the wavelength in a dielectric material and the propagation of electromagnetic waves?
The relationship between the wavelength in a dielectric material and the propagation of electromagnetic waves is that the wavelength of electromagnetic waves decreases when they travel through a dielectric material compared to when they travel through a vacuum. This is due to the slower speed of light in the dielectric material, which causes the waves to be compressed and have a shorter wavelength.
Why does your food travel so far?
Our food may travel long distances due to factors such as sourcing ingredients globally, transportation efficiency, and demand for diverse food options year-round. This can impact freshness, carbon footprint, and cost.
Why do acids travel so far before they fall as acid rain?
Acids can travel long distances in the atmosphere due to being carried by winds and air currents. This enables them to spread over large areas before eventually falling to the ground as acid rain. Furthermore, certain acids can react with other compounds in the atmosphere, forming aerosols that can travel even greater distances.

Additionally, long radio waves can penetrate through the ionosphere, allowing for communication beyond the horizon.
Do laser beams have one wavelength to and travel in one direction?
Yes, laser beams have one specific wavelength determined by the type of laser used. They also travel in one direction due to the tight focusing of light into a beam through the process of stimulated emission.
Is it true or false that laser beams have one wavelength and travel in one direction?
True, laser beams have one specific wavelength and typically travel in one direction due to the collimated nature of the light. This makes them ideal for applications like cutting, engraving, and communication.
