- X-ray.
- Radio waves.
- Ultraviolet waves.
What are some examples of waves in everyday life?
Examples of transverse waves include:
- ripples on the surface of water.
- vibrations in a guitar string.
- a Mexican wave in a sports stadium.
- electromagnetic waves – eg light waves, microwaves, radio waves.
- seismic S-waves.
Where do you see hear waves in your everyday life?
Waves in Everyday Life Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast.
How do we used electromagnetic waves in everyday life?
Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth.
How do we use sound waves in everyday life?
Ultrasound waves are used to detect objects. A ringing telephone, a honking horn, and the sound of a friend’s voice are all reminders of how important sound is. But sound has uses that go beyond communication. For example, some animals and people use reflected ultrasound waves to detect objects.
