Which are the metals which show and do not show photoelectric effect?
All metals will emit a photoelectric effect. However, alkali metals do so in the visible light spectrum, while other metals do so in near-ultraviolet light.The alkali metals are: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs), and Francium (Fr).
What did Einstein do in 1905?
While working as a paten clerk, he wrote 3 papers. 1. explaining Brownian motion 2. explaining the photoelectric effect and 3. the special theory of relativity.
What happens if light passes through a filter?
It depends on what kind of filter it is. A blue light filter, will cause the image appear to be bluer, while a red light filter will make the image reddererrr... ^^
Why does it not effect any of the light bulbs when you take one light bulb out from the parallel circuit?
EASY.The removed light bulb does not have any connection to the other light bulbs. While it's socket that was holding the lght bulb has power running through it to the other bulbs also.
Do nuclear weapons effect Global Warming?
Probably not. If anything, nuclear explosions should have a cooling effect, because they send so much junk (soot, ash) into the atmosphere. It stays up there for a while, blocking light from the sun. This is the feared "nuclear winter" that would happen if a major nuclear exchange occurred. Volcanoes have a similar effect, but it takes quite a large eruption to have a noticeable effect.
Is Compton effect reverse process of x-rays production?
No,The production of x rays is a reverse process of photoelectric effect. X rays are produced when target metal is bombarded by electrons while in photoelectric effect, the electron are produced when light waves are incident on a metal surface.

Whats a antonym for cause and effect?
The antonym for cause is result and effect while the antonym of effect is agency.

Why is photosynthesis called the photoelectric effect?
When light over a cretain frequency hits a conducting metal with lots of delocalised electrons, it transfers a lot of energy, and after a while it will start emmitting electrons. The only condition is f>fo (i.e the frequency is bigger than the minimum frequency). The minimum frequency is about 540nm- about green visible light. The rate of emmission can be changed with a circuit with an anode and a cathode on either end of the photoelectrisising metal. The effect can be demonstrated with a Gold Leaf electroscope. Before light is shone, the whole electroscope is neutral, and the gold leaf is stationary. When the electroscope loses electrons in from photoectrisisng the gold leaf is repelled as they now have opposite charge. The effect has many uses, including solar power.
What are the cause and effect in the sentence The painter could not sell his paintings because he loved them very much?
The cause is "The painter could not sell his paintings" while the effect is "because he loved them very much". The cause is "what" in a statement. The effect could be described as the "why" in a statement.
Why are potassium and caesium rather than lithim used in photoelectric cells?
Potassium can loose electron easily . Comparatively Lithium have high ionisation energy and low level of loosing electron while absorbing light energy.
What are the cause or effects of HIV and STD?
Cause- is the specific action a person does which leads to effect or consequence of the action undertaken by the person.Effect-of that action may be good or bad and may be determined by the cause. In short, cause is the primary action while the effect is the result of that action.
What could cause my Ford focus to have trouble accelerating while the engine light is on?
You have no wheels. - Geoff
When two factors are correlated a cause and effect relationship exists between the factors?
Nope, correlation simply links two factors together, while a cause and effect relationship finds that one factor causes change in the other. Generally, cause and effect is harder to establish and requires more clinical rigour (eg. with experiments).
What would cause the fasten safety belt light symbol to go on while I am driving?
Not fastening your seatbelt.
