What is the speed of electromagnetic waves in air and water?
The speed of electromagnetic waves in air is approximately 299,792 kilometers per second (km/s), which is the speed of light in a vacuum. In water, electromagnetic waves travel slower at around 225,000 km/s due to the higher refractive index of water compared to air.
What speed do television waves travel in air?
If the information for television goes through the air, the waves used are electromagnetic waves; specifically of the type called RADIO WAVES.All electromagnetic waves travel at the speed of light when in a vacuum: about 300,000 km/second. In air, the speed is almost the same as in a vacuum.
Is the speed of a sound wave slower than a electromagnetic wave?
Yes, the speed of sound waves is slower than the speed of electromagnetic waves. Sound waves travel through a medium, such as air or water, at a speed that depends on the properties of that medium. Electromagnetic waves, such as light, can travel through a vacuum at a speed of about 300,000 kilometers per second.
How are electromagnetic and mechanicl waves different?
Electromagnetic waves are oscillations of electric and magnetic fields that do not require a medium to propagate, while mechanical waves require a medium such as air or water to transfer energy. Electromagnetic waves can travel through a vacuum, whereas mechanical waves cannot. Additionally, electromagnetic waves travel at the speed of light, while the speed of mechanical waves depends on the properties of the medium.
Which phenomenon do em waves exhibit that sound waves do not?
Electromagnetic waves can travel through a vacuum, while sound waves require a medium (such as air, water, or solids) to propagate. Additionally, electromagnetic waves can travel at the speed of light, while sound waves travel at a much slower speed.

What happens to the speed of electromagnetic waves when they go from air to water?
The speed of electromagnetic waves decreases when they transition from air to water because water has a higher refractive index than air. This causes the waves to bend or refract as they enter the water.

What is it that all electromagnetic waves do the same?
All electromagnetic waves travel at the speed of light in a vacuum and can be characterized by their wavelength and frequency.
What are waves that travel through space at the speed of light called?
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
What is the difference of electromagnetic waves and mechanical waves?
Electromagnetic waves do not require a medium to propagate and can travel through a vacuum, whereas mechanical waves require a medium (such as air, water, or solids) to travel through. Electromagnetic waves consist of oscillating electric and magnetic fields, while mechanical waves are produced by the vibration of particles in the medium. Electromagnetic waves can travel at the speed of light, while the speed of mechanical waves depends on the properties of the medium.
Electromagnetic waves may exist at?
Electromagnetic waves can exist only at one speed.
Do all em eaves travel at the same speed?
No, not all electromagnetic waves travel at the same speed. The speed of an electromagnetic wave depends on the medium through which it is traveling. In a vacuum, all electromagnetic waves travel at the speed of light, which is approximately 299,792 kilometers per second.
How do the velocities of a sound wave and electromagnetic wave compare to each other?
In air at sea level, the speed of electromagnetic waves isroughly 882 thousand times the speed of sound.
