Yes, this is called the photoelectric effect. Discovered my Einstein.

What do you think could travel faster than light a cheetah a bullet sound the space shuttle or highly energetic electrons?

Highly energetic electrons could potentially travel faster than light, as they can achieve speeds close to the speed of light in a vacuum. However, nothing with mass can surpass the speed of light in a vacuum, according to the theory of relativity.


Could you survive being sucked into a black hole?

No, it is highly unlikely that anyone could survive being sucked into a black hole due to the extreme gravitational forces and intense tidal forces that would tear apart anything that gets too close.


The emission of electrons in high-vacuum tubes is caused by?

The heating by the filament causes the electrons to "boil off". Edison noted this phenomena and it was later picked up by Fleming who used a "grid" which could control the flow of the electrons by introducting a repelling field between the Cathode (heated element that emitted the electrons) and the anode that attracted the free electrons, thus the "Fleming Valve" was invented (the vacuum tube.


Could beryllium lose or gain electrons?

Beryllium typically loses electrons to form a +2 ionic charge. It is easier for beryllium to lose its outermost electrons than to gain new ones due to its small atomic size.


What is the procedure in Davisson-Germer experiment?

The Davisson-Germer experiment demonstrated the wave nature of the electron, confirming the earlier hypothesis of de Broglie. Putting wave-particle duality on a firm experimental footing, it represented a major step forward in the development of quantum mechanics. The Bragg Lawfor diffraction had been applied to x-ray diffraction, but this was the first application to particle waves.Davisson and Germer designed and built a vacuum apparatus for the purpose of measuring the energies of electrons scattered from a metal surface. Electrons from a heated filament were accelerated by a voltage and allowed to strike the surface of nickel metal. The electron beam was directed at the nickel target, which could be rotated to observe angular dependance of the scattered electrons. Their electron detector (which was also called as a Faraday box) was mounted on an arc so that it could be rotated to observe electrons at different angles. It was a great surprise to them to find that, at certain angles there was a peak in the intensity of the scattered electron beam. This peak indicated wave behaviour for the electrons, and could be interpreted by the Bragg Law to give values for the lattice spacing in the nickel crystal.

How can you write a sentence using strung?

His strung nerves made it difficult for him to relax Could also say - he is highly strung meaning intense, anxious etc.


How could you determine the volume of a solid that has a surface too highly irregular to measure?

Immerse it in a liquid, and measure how much the level of the liquid rises.


Was there ever life on Jupiter?

There is no evidence to suggest that there has ever been life on Jupiter. The extreme conditions on the planet, including its lack of a solid surface and intense radiation, make it highly unlikely that any form of life could exist there.

Could the earth crust melt?

The earth's crust can melt under extreme conditions, such as intense heat from volcanic activity. This can lead to the formation of magma which can eventually erupt onto the surface as lava.


A word used to describe a color which is intense and glaring?

A descriptive word for a color that is intense and blaring could be "Brilliant."


How could they survive the intense UV radiation exposure?

The answer will depend on what they are.


Is the atomic number of an atom is 11 how many electrons does the atom have?

You cannot know for sure withoutmore information. An electrically neutral sodium atom (sodium has at. no. 11) will have the same number of electrons as protons; atomic number tells you the number of protons, so this atom has 11 protons and would have 11 electrons if electrically neutral, however, if the atom is charged, it could have more or fewer electrons. Sodium atoms in stars are highly ionized and may have just a few if any any electrons.

Why life hasn't been found yet in neptune?

Most likely there is no life there. Neptune is a gas giant, meaning it has no surface and its atmosphere is extremely cold. It is highly unlikely that anything could live there.
