What do sound and light waves carry?
Sound waves and light waves carry energy that enable you to hear and see the world around you.
What are the types of waves of light and sound?
Sound is a longitudinal wave, while light is a transverse wave. Polarization requires the direction of the wave to be perpendicular to the direction of propogation; only light can do this. Doppler effect, refraction, and interference occur in both wave types.
What types of waves are used for communication?
Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air.
What EM waves are used in texting?
Cell phones use antennae to transmit and receive radio waves that carry binary information. Every cell tower presides over an area of land, where it receives and transmits radio waves. When a text message is written, it is transmitted as binary code using a particular frequency of radio waves specific to that user.
Which wave is used for cellular communication?
radio waves
Your mobile uses radio waves to transmit signals to a network of base stations. The radio waves used by mobile devices are part of the electromagnetic wave spectrum and travel at the speed of light. How does a mobile device connect to the internet?
What type of light wave is satellite television and communication?
Radio waves
Radio waves are used to carry satellite signals. These waves travel at 300,000 km/s (the speed of light).
What do sound waves and light waves carry energy for?
Sound waves and light waves carry energy that enable you to hear and see the world around you. Write a short paragraph describing water waves you have seen. Science Journal Waves, Sound, and Light Mark A. Johnson/CORBIS 681-S1-MSS05 8/13/04 4:59 PM Page 692 693 Wave Properties If you drop a pebble into a pool of water, you
What is the medium for sound waves?
The medium for most waves is usually apparent. For a string wave, the medium is a string. For sound waves, the medium is air. What is the medium for light? We know that we can detect the light from distant stars and galaxies, so apparently light can travel through empty space.
How do we use electromagnetic waves to communicate?
using waves to communicate As we communicate by voice, modulating the mechanical waves emitted by our vocal cords, great physicists such as Hertz, Tesla, Branly and Marconi understood that it was possible to use electromagnetic waves to convey information through the air.
How do we know about waves?
You know about water waves because you can see and feel their movement, but there are other types of waves, also. Different types of waves carry signals to televisions and radios. Sound and light waves move all around you and enable you to hear and see. Waves are even responsible for the damage caused by earthquakes.
