In any metal, there are free surface electrons. For these electrons to escape from the surface of a metal, they require a specific amount of energy, called the 'Work Function'. There are many sources of t...

When the string is plucked, waves will travel from the point where it was plucked to the fixed ends, which cannot move and so must be nodes. The waves will reflect, and the superposition of the reflected ...

^A_Z X --> ^{A - 4}_{z - 2}Y + ⁴₂α
During alpha-decay, the nuclus emits an alpha particle which consists of two protons and two neut...

Ve = kQ/r = ((8.99 * 10^9) * (1.6 * 10 ^-19))/(0.5 * 10^-10) = 28.77 = 29 V

The photo-electric effect is the way in which electrons are released from the surface of a metal when there is an incident light ray. The particle model of light, as part of wave-particle duality, suggest...
