What are the 7 electromagnetic waves in order?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays..
Is anything faster than light?
There is no limit to how fast the universe can expand, says physicist Charles Bennett of Johns Hopkins University. Einstein’s theory that nothing can travel faster than the speed of light in a vacuum still holds true, because space itself is stretching, and space is nothing.
What is P wave and S wave?
Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves). P-waves are compression waves. They can propagate in solid or liquid material. S-waves are shear waves. They only propagate in solid material.
Are higher frequencies more dangerous?
According to experts on the biological effects of electromagnetic radiation, radio waves become safer at higher frequencies, not more dangerous. (Extremely high-frequency energies, such as X-rays, behave differently and do pose a health risk.) In his research, Dr.
Which wavelengths are most dangerous to humans?
Ultraviolet radiation of wavelengths shorter than 300 nm (actinic rays) can damage the corneal epithelium. This is most commonly the result of exposure to the sun at high altitude, and in areas where shorter wavelengths are readily reflected from bright surfaces, such as snow, water, and sand.
What is faster alpha beta or gamma?
Ans 1: (Master Answer) Alpha particles leaves the nucleus of an unstable atom at a speed of 16,000 kilometres per second, around a tenth the speed of light. Beta particles travel at a speed of 270,000 kilometres per second, around 98% of speed of light. Gamma particles travel at the speed of light.
Does sound travel faster in water or air?
Sound travels faster in water compared with air because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster.
Why red light travels maximum distance?
Light travels in waves, so it covers more distance than a straight line.
Which electromagnetic wave travels the fastest?
Photons travel in harmonic waves at the fastest speed possible in the universe: 186,282 miles per second (299,792,458 meters per second) in a vacuum, also known as the speed of light.
Which wave travels at the fastest rate?
In a vacuum, all electromagnetic waves travel at 3 × 10 8 m s − 1 – the fastest speed possible. When electromagnetic waves travel through matter (for example, light passing through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum.
What type of radiation travels the fastest?
Gamma raysLight as well as Gamma rays are electromagnetic in nature and all electromagnetic waves travel with same speed in vacuum. However in a medium, Gamma rays having the highest frequency among all electromagnetic radiation travel the fastest.
What type of wave travels the slowest?
Surface wavesSurface waves are the slowest of all seismic waves. They travel at 2.5 km (1.5 miles) per second. There are two types of surface waves.
Which wave causes the most damage?
Surface waves, in contrast to body waves can only move along the surface. They arrive after the main P and S waves and are confined to the outer layers of the Earth. They cause the most surface destruction. Earthquake surface waves are divided into two different categories: Love and Rayleigh.
Which electromagnetic wave has the most energy?
gamma-raysRadio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
Which is the fastest wave?
P-waveThe fastest seismic wave is the primary wave, or the P-wave. These waves move through solid rock and liquid rock alike at high speeds, since they…
What is the heaviest form of radiation?
alpha particlesThe first is an alpha particle. These particles consist of two protons and two neutrons and are the heaviest type of radiation particle. Many of the naturally occurring radioactive materials in the earth, like uranium and thorium, emit alpha particles.
