When a body moves through a fluid, it experiences an opposing force which tries to oppose its motion through the fluid. This opposing force is known as the drag force....
(b) may be longitudinal
(d) may be transverse.
EXPLANATION:
Both types of wave can travel through a solid. So it can either be a longitudinal wave or a transverse wave.
(a) longitudinal stationary waves
EXPLANATION:
An organ pipe open at both ends contains sound waves which are longitudinal waves, so the option (c) and (d) are not true. When the waves enter...
(c) both particle and wave phenomenon.
EXPLANATION:
The photoelectric effect shows it as a particle phenomenon while the interference and diffraction of light shows it as a wave phenomenon. Hence duel...
(d) Polarization.
EXPLANATION:
The reflection, interference and diffraction effects are shown by both transverse and longitudinal waves. But polarization is only possible with a transverse wave because the transverse displacement of...
When a wave propagates in a straight line, from the transmitting antenna to the receiving antenna, its mode of propagation is called space wave communication.
Frequency range: Above 40MHz
ʎ=h/mv derive from this equation for an electron and proton
V1/v2 =m2/m1
=1.6725 x 10-27/9.1095 x 10-31
=1836
Velocity of electron= velocity of proton x 1836
