what types of electromagnetic radiation can reach earth?
29215
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.

['Electromagnetic radiation can travel through empty space. Most other types of waves must travel through some sort of substance. ... ', 'The speed of light is always a constant. ... ', 'Wavelengths are measured between the distances of either crests or troughs.']

Because the radiation from the sun travels to Earth in varying wavelengths, scientists consider them to be a spectrum. Which statement describes an electromagnetic wave with a long wavelength? It has a low frequency and needs a medium to travel through.

Radio waves can penetrate nonconducting materials, such as wood, bricks, and concrete, fairly well. They cannot pass through electrical conductors, such as water or metals. Above ν = 40 MHz, radio waves from deep space can penetrate Earth's atmosphere.

D) Ultraviolet and infrared radiation make up the greatest amount of electromagnetic energy reaching Earth's surface.

Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes. All light, or electromagnetic radiation, travels through space at 186,000 miles (300,000 kilometers) per second — the speed of light.

Some of this energy is transferred to the atmosphere by conduction and convection . The Earth also radiates lower frequency infrared radiation. Some of this infrared radiation is transmitted through the atmosphere back out into space, and some is absorbed by greenhouse gases in the atmosphere.
1327146
Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices.

Electromagnetic waves are electric and magnetic fields traveling through empty space with the speed of light c. ... The wavelength λ of this wave is given by λ = c/f. Electromagnetic waves transport energy through space. This energy can be delivered to charged particles a large distance away from the source.

Electromagnetic radiation travels in wave packets known as photons that consist of propagating electric and magnetic fields. These photons undergo absorption when they transfer energy to atoms within a substance they are striking instead of transmitting through or reflecting off of it.

This light, however, is only one type of electromagnetic radiation. Electromagnetic radiation comes in a range of energies, known as the electromagnetic spectrum. The spectrum consists of radiation such as gamma rays, x-rays, ultraviolet, visible, infrared and radio.
1216739
Electromagnetic radiation, in classical physics, the flow of energy at the universal speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves, visible light, and gamma rays.

Electromagnetic waves. Electromagnetic (EM) waves are changing electric and magnetic fields, transporting energy and momentum through space. EM waves are solutions of Maxwell's equations, which are the fundamental equations of electrodynamics. EM waves require no medium, they can travel through empty space.

These electric and magnetic waves travel perpendicular to each other and have certain characteristics, including amplitude, wavelength, and frequency. General Properties of all electromagnetic radiation: Electromagnetic radiation can travel through empty space.

Electromagnetic Radiation. Electromagnetic radiation is energy that is propagated through free space or through a material medium in the form of electromagnetic waves, such as radio waves, visible light, and gamma rays. The term also refers to the emission and transmission of such radiant energy.

The 21 cm spectral line appears within the radio spectrum (in the L band of the UHF band of the microwave window to be exact). Electromagnetic energy in this range can easily pass through the Earth's atmosphere and be observed from the Earth with little interference.

Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.
