Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927)
An experiment which conclusively confirmed the wave nature of electrons; diffraction patterns were observed through an electron beam penetrating in a nickel target.
Can slide emitting optics is bright or brighter than neon? Fiber optics can be made to be brighter than neon but merely for very short distances. Let an illustration, of a gard
What is the significance of negative work?
The effects of back emf on circuit current: In proving the time constant, it was stated that, at the instant the switch is closed, the current (I) is zero. This is because, at
Q. Why does the sky appear blue in colour? As-per to the Rayleigh's scattering law the shorter wavelengths are scattered much more than the longer wavelengths. The blue look o
Discharging: The cell is connected across some load during discharging. As the direction of current by the cell is reversed during discharging the negative ions go in the directio
If a negative charged particle enters a magnetic field perpendicularly,then it follows a circular path.In what directn does the particle move---in clockwise or anticlockwise? So
Fresnel''s diffraction due to a straight edge?
Brewster's law (D. Brewster) The extent of the polarization of light reflected through a transparent surface is maximum while the reflected ray is at right angles to the refra
Identify the action reaction pairs in the following situations: a. Snowball hits a girl in the back. Snowball pushes girl's back; girl's back pushes on snowball. b. A base
In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use
