Radio waves
, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation
What is the weakest type of wave?
The Electromagnetic spectrum lists the most powerful EMR, gamma rays, to the least powerful EMR,
radio waves
. In addition, the highest energy waves (gamma, x-ray) have the shortest wavelengths. The lowest energy waves, radio waves, have longest wavelengths.
What is the lowest wave called?
The highest part of the wave is called the crest. The lowest part is called
the trough
.
What are the 7 types of radiation?
The electromagnetic spectrum includes, from longest wavelength to shortest:
radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays
. To tour the electromagnetic spectrum, follow the links below!
What are the 5 types of radiation?
- electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)
- particle radiation, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation (particles of non-zero rest energy)
What are the 2 types of waves?
Waves come in two kinds,
longitudinal and transverse
. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
What are the 4 parts of a wave?
Wave Crest
: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest. Wave Length: The distance between two consecutive wave crests or between two consecutive wave troughs.
What is called wave height?
As is shown on the figure, wave height is defined as
the height of the wave from the wave top
, called the wave crest to the bottom of the wave, called the wave trough. The wave length is defined as the horizontal distance between two successive crests or troughs.
What are the three major types of radiation?
The three most common types of radiation are
alpha particles, beta particles, and gamma rays
. Alpha radiation is not able to penetrate skin.
What are the 7 types of light?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are:
radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays
.
What stops each type of radiation?
Depending on their energy, they can be stopped by
a thin piece of aluminum foil
, or they can penetrate several inches of lead. In this experiment, we study the penetrating power of each type of radiation.
What types of radiation are harmful?
Radioactive materials that emit alpha and beta particles are most harmful when swallowed, inhaled, absorbed, or injected.
Gamma rays
are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin.
What are 4 examples of radiation?
- ultraviolet light from the sun.
- heat from a stove burner.
- visible light from a candle.
- x-rays from an x-ray machine.
- alpha particles emitted from the radioactive decay of uranium.
- sound waves from your stereo.
- microwaves from a microwave oven.
- electromagnetic radiation from your cell phone.
Which type of radiation has the most energy?
Gamma rays
have the highest energies and shortest wavelengths on the electromagnetic spectrum.
What are the 5 properties of waves?
They include
amplitude, frequency, period, wavelength, speed, and phase
. Each of these properties is described in more detail below.
What are the classification of waves?
There are two basic types of wave motion for mechanical waves:
longitudinal waves and transverse waves
. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.
