a) The medium separated up into a number of components. Every part is vibrating up and down as a whole.
b) All the molecules in single particular segment vibrate in the same medium. Molecules in two consecutive segments vary in phase by 1800.
c) All the molecules except those at nodes, implement simple harmonic motion about their mean position with the similar time period.
d) The magnitude of vibration of particles differs from zero at nodes to maximum at antinodes (2a).
e) All positions pass their mean position twice in single time period.
The stopping potential of a photocell is 2.3 V. What is the initial velocity of an emitted photoelectron that is brought to a stop by the photocell?
In an adiabatic process, the body neither absorbs heat nor does it refuse energy, i.e. in this phenomena there is no heat exchange (Δ Q = 0). Thus from first law of thermodynam
