Black body radiation of the emission o light from metal surfaces false or true?
False. Black body radiation refers to the emission of light from an object that absorbs all incident radiation. While metals can emit light, the term "black body radiation" specifically refers to the emission from an idealized object, called a black body, which is not typically applicable to metal surfaces.
What is the difference between field emission and photoelectric emission?
* emisssion of electron from the surface of the metal when light of suitable frequency falls-photoelectric emission. * emision of electron from the metal by quantum tunnling of electron.
What is the time lag between the arrival of light at a metal surface and the emission of photoelectron?
no time lag.................
Which statement best describes the light that will cause emission of electrons from a given metal through the photoelectric effect?
This is an interaction between photons and the surface of the metal.
A rough surface reflects light in many directions.?
All surfaces reflect light. However, only the smoothest surfaces reflect all light in one direction. These are shiny and include mirrors and metal. Some surfaces just reflect the light in all directions, which is why you cannot see the reflection.
Which microscope is often used to view metal surfaces?
Metal samples among others can be viewed by a light microscope. The light microscope, also known as an optical microscope, can view microorganisms.
What types of reflective surfaces are there?
Some common types of reflective surfaces include mirrors, glass, polished metal, water, and glossy surfaces like polished marble or granite. These surfaces are able to reflect light due to their smooth and flat characteristics, which allow for minimal light absorption and maximum reflection.
What is the difference between the way black and white surfaces affect light?
White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.
What has the author I Garnett Barber written?
I. Garnett Barber has written: 'Secondary electron emission from copper surfaces' -- subject(s): Secondary electron emission
What is an electron emission?
The process in which an electron emit from metal surface into surrounding is known as electrons emission
What short for light amplification by stimulated emission of radiation?
Laser is short of light amplification by stimulated emission of radiation.
Does a rough surface reflect light in many directions?
Highly polished, shiny surfaces reflect light the best as they are REFLECTive. White or bright surfaces also reflect light well. Dull, Matt surfaces are the worst reflecters of light
