Answer:
the oscillations of the electrons must be in the 10⁸ Hz = 100 MHz range
Explanation:
The speed of a wave of radio, television, light, heat, all are manifestations of electromagnetic waves that are oscillations of electric and magnetic fields that support each other, the speed of all these waves is the same and the vacuum is equal to c = 3 108 m / s
All waves have a relationship between the speed of the wave, its frequency and wavelength
c = λ f
f = c /λ
for this case lam = 1 m
f = 3 10⁸/1
f = 3 10⁸ Hz
the oscillations of the electrons must be in the MHz range
It should be clarified that the speed of light in air is a little lower
n = c / v
v = c / n
the refractive index of vacuum is n = 1 and the refractive index of air is n = 1.000002
Answer:
Explanation:
The equations of kinematics will be used to solve this question:
At its maximum height, the projectile has zero velocity in the y-direction. But its velocity in the x-direction is unaffected.
First, let's apply the above equations to the x-direction.
There is no acceleration in the x-direction. So, its velocity in the x-direction is constant during the motion.
Therefore, the velocity vector of the projectile is
The speed of the projectile is the same.
The acceleration vector is constant during the motion and equal to the gravitational acceleration, which is -9.8 downwards.
