How do magnetic fields impact the propagation of radio waves?
Magnetic fields can affect the propagation of radio waves by causing them to bend or refract as they travel through the atmosphere. This can result in changes to the direction and strength of the radio waves, impacting communication and signal quality.
AM radio waves are able to traves farther than FM radio waves because?
AM radio waves have longer wavelengths compared to FM radio waves, allowing them to diffract or bend around obstacles such as buildings and hills. This enables AM radio waves to travel greater distances and provide better coverage in areas with obstructions. FM radio waves, on the other hand, travel in straight lines and are more affected by obstacles.
Can you explain how diffraction occurs with radio waves?
Diffraction with radio waves happens when the waves encounter an obstacle or opening that is similar in size to their wavelength. This causes the waves to bend around the obstacle or spread out after passing through the opening, resulting in a change in their direction and intensity.
Why gamma rays do not bend?
Gamma rays do not bend because they are high-energy electromagnetic radiation that travels in straight lines. Unlike charged particles, gamma rays are not influenced by magnetic or electric fields that would cause them to bend. Therefore, they continue to travel in straight paths until they are either absorbed or interact with matter.
Which wave diffracts the most when encountering an obsta cle?
Longer waves, such as radio waves, diffract the most when encountering an obstacle because their longer wavelengths enable them to bend around the obstacle more effectively. This phenomenon is known as diffraction, where waves bend around corners or spread out when encountering an obstacle.

Does the ionosphere bend radio waves back toward the earth?
it refracts the radio waves back towards the earth
Is there any magnetic effect on light radiation?
Light, or electromagnetic radiation, is generally unaffected by magnetic fields. Magnetic fields don't "bend" light, though photons will follow the curvature of spacetime around massive gravitational fields.
How do very long radio waves reach stations beyond the curvature of the Earth?
Radio waves, like all forms of electro magnetic radiation are affected by gravity, so the Earth's mass helps to bend the radio waves to an extent. Beyond that, radio waves can be reflected naturally by atmospheric conditions, but generally, when a radio signal needs to be transmitted a significant distance, it is done by a series of radio towers in relay.AnswerThe condition is called 'skip'. The waves bounce off the ionisphere and back to earth way past the curvature.

What form of electromagnetic waves can bend easily?
the very low frequencies up through the AM radio broadcast band.
What are magnetic fields used to contain?
Magnetic fields are used to contain a variety of particles. Varying strengths can contain different materials. Mainly used to contain metal (iron and steel) and plasma. When the magnetic field is strong enough it can bend light and even attract nonmetallic objects that accept a charge.
What waves bend?
Waves that bendm

What two processes can cause waves to bend?
diffraction and refraction are two processes that can bend waves
