An electromagnetic wave, in its simplest description, is a wave that as it propagates keeps converting its magnetic field into an electric field while converting its electric field into a magnetic field.
What else can I help you with?
What does contrast electromagnetic waves with water and sound waves mean?
It means explain how electromagnetic waves are different than water and sound waves.
Electromagnetic waves are not mechanical waves which means they can travel in a?
vacuum
What is the relationship between the distance from a source of electromagnetic waves and the electromagnetic wave intensity at that distance?
The relationship between the distance from a source of electromagnetic waves and the electromagnetic wave intensity at that distance is inversely proportional. This means that as the distance from the source increases, the intensity of the electromagnetic waves decreases.
Are electromagnetic waves transverse or compressional waves?
Electromagnetic waves are transverse waves. This means that the oscillations of the electric and magnetic fields that make up the wave occur perpendicular to the direction of wave propagation. Unlike compressional waves, electromagnetic waves do not require a medium to travel through.
Technology of sending out information by means of electromagnetic waves?
microwaves
What radiation waves does an electric radio produce?
The radio receptor receives electromagnetic waves from a broadcast station.These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.
What is the relationship between frequency and energy in the context of electromagnetic waves?
The relationship between frequency and energy in electromagnetic waves is that higher frequency waves have higher energy. This means that as the frequency of an electromagnetic wave increases, so does its energy.
How are electromagnetic waves different from other types of waves, and why are electromagnetic waves classified as transverse waves?
Electromagnetic waves are different from other types of waves because they do not require a medium to travel through, unlike sound waves which need a medium like air or water. Electromagnetic waves are classified as transverse waves because their oscillations are perpendicular to the direction of their propagation. This means that the electric and magnetic fields in electromagnetic waves vibrate at right angles to the direction the wave is moving.
What happens when the wavelength of electromagnetic waves decreases?
When the wavelength of electromagnetic waves decreases, the frequency of the waves increases. This means that the waves carry more energy and are more powerful. Lower wavelengths are associated with higher energy electromagnetic radiation such as X-rays and gamma rays.
What medium is needed for electromagnetic waves?
Electromagnetic waves can travel through a vacuum, which means they do not need a medium to propagate. This is a unique feature of electromagnetic radiation compared to mechanical waves like sound waves which require a medium, such as air or water, to travel through.
Is electromagnetic waves are transverse in nature?
Yes, electromagnetic waves are transverse in nature. This means that the electric and magnetic fields oscillate perpendicular to the direction of wave propagation.
What three ways can differ electromagnetic waves from sound waves?
Electromagnetic waves are transverse in nature where as sound waves are longitudinal. Electromagnetic waves can pass even through vacuum but sound waves are mechanical waves that means it needs badly a material medium Sound waves can be sensed by ear where as electromagnetic waves are sensed by eyes.
