What are two types of electromagnetic radiation?

What are two types of electromagnetic radiation?

Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

What’s the meaning of waves?

1 : a moving ridge on the surface of water. 2 : a waving motion a wave of the hand. 3 : something that swells and dies away A wave of anger came over her. 4 : a rolling movement passing along a surface or through the air waves of grain. 5 : a curving shape or series of curving shapes hair with waves.

What does waves mean in science?

A wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium. That medium moves back and forth repeatedly, returning to its original position. But the wave travels along the medium.

What does wave top mean?

wavetop (plural wavetops) The top of a wave of liquid.

What type of waves Cannot be transmitted through empty space?

For example, water waves, earthquake/seismic waves, sound waves, and the waves that travel down a rope or spring are also mechanical waves. Sound waves, as with all mechanical waves, cannot be transferred or transmitted through empty space (vacuum).

What are three interactions of sound waves?

Three ways that waves may interact with matter are reflection, refraction, and diffraction. Reflection occurs when waves bounce back from a surface that they cannot pass through.

What is it called when a wave bounces back and comes back to the source?

It is called an echo or a reflection when a wave bounces back and comes back to the source.

When a wave bounces back after hitting a barrier is called what?

The bouncing back of a wave after it strikes a barrier is called refraction. When frequency increases, diffraction increases. mechanical waves are waves that transfer energy through empty space. reflection is the bending of a wave as it enters a new medium at an angle other than 90 degrees.

What is it called when two waves overlap?

What occurs when two or more waves pass through one another. Also called superposition. Constructive interference. When overlapping waves produce a wave with an amplitude that is the sum of the individual waves.

What are the basic properties of waves?

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. A wave can be described by its length, height (amplitude) and frequency. All waves can be thought of as a disturbance that transfers energy.

What is the meaning of resonance?

being resonant

What are the applications of resonant frequency?

Applications of the Resonant RLC Circuits

• Oscillator circuit, radio receivers, and television sets are used for the tuning purpose.
• The series and RLC circuit mainly involves in signal processing and communication system.
• The Series resonant LC circuit is used to provide voltage magnification.

What is meant by resonant frequency?

Resonant frequency is the oscillation of a system at its natural or unforced resonance. Resonance occurs when a system is able to store and easily transfer energy between different storage modes, such as Kinetic energy or Potential energy as you would find with a simple pendulum.

What is meant by Q factor?

In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. Q factor is alternatively defined as the ratio of a resonator’s centre frequency to its bandwidth when subject to an oscillating driving force.
