How does the photoelectric effect support particle theory of light?

Posted by Mugha ? 6 years, 7 months ago

CBSE > Class 12 > Physics

1 answers

Gaurav Seth 6 years, 7 months ago

The photoelectric effect supports a particle theory of light in that it behaves like an elastic collision (one that conserves mechanical energy) between two particles, the photon of light and the electron of the metal.

If you shine light on a metal of any intensity with energy below the binding energy of an electron, no electrons from the metal will be ejected. As soon as the frequency of light is high enough such that the energy exceeds the binding energy, the electron from the metal can be knocked off the metal.

If the energy of the photon that hits the metal is hν, then energy will be conserved in the collision so that

hν=BE+KEelectron

The energy before the collision is hν. The minimum amount of energy needed to eject the electron is the binding energy, BE. However much hν exceeds the binding energy will be the kinetic energy KE of the ejected electron.

Conservation of energy in collisions is particle like behavior and thus the photoelectric effect supports light's particle like behavior.

Gaurav Seth 6 years, 7 months ago

There may be various reasons for the falling nature or downward sloping of demand curve. Some of them are as follows:

The following are the Causes of Downward Sloping of Demand Curve

Law of diminishing the marginal utility
Substitution effect
Income effect
New buyers
Old buyers

What industrial licensing ?how does it impact allocation of resources

Posted by Sandeep Kumar 6 years, 7 months ago

CBSE > Class 12 > Economics

2 answers

Gaurav Seth 6 years, 7 months ago

Industrial licensing is an authority issued by the government organisation to permit the institution or organisation for starting an industry .

Impact on allocation:

It REGULATES the allocation of resources for different uses as whenever the company will expand its production capacity it will be required to acquire a licence and thus it will give the govt. an opportunity to keep a check that where the resources are going , for what purpose they are being used and if scarce resources are properly utilised or not. Without license, any industry would use or even exploit the resources no matter how scarce they are
