Which of these electromagnetic waves has the shortest?

Gamma rays

Which are characteristics of electromagnetic waves check all that apply?

travel in straight lines and can bounce off surfaces. travel through space at the speed of light. travel only through matter. travel only through space.

Does most of the electromagnetic spectrum consists of visible light?

Most of the electromagnetic spectrum consists of visible light. Energy emitted by vibrating electric charges is carried by electromagnetic waves. Light sometimes acts as a wave and sometimes as a particle.

What is the source of electromagnetic waves quizlet?

Electromagnetic waves are produced when an electric charge vibrates or accelerates.

What is the source of all electromagnetic waves?

the sun

What is the source of almost all electromagnetic waves?

Stars and lightning are natural sources of radio waves, but these are also produced by the antenna on a radio transmitter. Many sources of electromagnetic radiation come from man-made technology. On the other side of the spectrum, we have ultraviolet radiation, which is emitted by black lights and fluorescent lamps.

Is red light higher energy than blue?

Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers. Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.

Does red light travel faster than blue light in a vacuum?

Because the number of subquantum energy in a red photon is less than that of a blue photon, red photon interactions are less than the blue photon in the medium. So, the red light travels faster than the blue light.

What color will we see if an object is absorbing all of the colors of light?

A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light. It reflects yellow light and we see it as yellow.

What happens when light interacts with matter?

When light interacts with matter it can do one of several things, depending on its wavelength and what kind of matter it encounters: it can be transmitted, reflected, refracted, diffracted, adsorbed or scattered. When this happens the light slows down and changes direction.

What are 3 ways light can interact with matter?

How does light interact with matter? – Matter can emit light, absorb light, transmit light, and reflect (or scatter) light.

What are 3 different ways light interacts with matter?

Light can interact with matter in three ways: absorption, transmission, and reflection. 1. ABSORPTION – When a light wave with a identical frequency to an electron’s natural frequency “impinges” upon an atom, the electrons will begin to vibrate as a result (almost like they are “set in motion”).

What happens to energy when light is reflected off a material?

The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object. When this occurs, objects have a tendency to selectively absorb, reflect or transmit light certain frequencies.

What is the difference between transmitted and reflected light?

Reflection is the process by which electromagnetic radiation is returned either at the boundary between two media (surface reflection) or at the interior of a medium (volume reflection), whereas transmission is the passage of electromagnetic radiation through a medium.

Can electromagnetic waves travel in vacuum?

These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

What do electromagnetic waves travel fastest through?

Electromagnetic waves- travel fastest in empty space and slowest in solids. 4. Waves can change speeds when going from 1 type of medium to a different type 5. In a same type of medium the speed of waves is constant.

How do electromagnetic waves affect us?

At low frequencies, external electric and magnetic fields induce small circulating currents within the body. The main effect of radiofrequency electromagnetic fields is heating of body tissues. There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health.
