frequency of the ultrasound given as
speed of the wave is
Now the wavelength is given as
now we know that distance between two consecutive antinodes is always half of wavelength
so we have
d = 0.75 mm
Answer:
The electric and magnetic fields gradually increase.
Explanation:
Time constant in RL circuits, denoted by τ, is equal to the value of L / R which is the value of the inductor over the resistor. It is used to calculate the point when the current will reach the maximum value in the steady state of the circuit. Because of this behavior of the circuit, the magnetic field and the electric field gradually increase to their maximum values.
I hope this answer helps.
The photon's energy is equal to
(its frequency) times (Planck's Konstant ... 6.626 x 10⁻³⁴ m²-kg/sec)
