Wave speed = frequency * wavelength
Rearrange so it's equal to wavelength. Do this by diving both sides by frequency to leave you with:
Wave speed / frequency = wavelength
340 / 265 = 1.2830 m
Answer:
B = 32.17 x 10^-8 Tesla
u = 8.24 x 10^-8 J/m^3
P/A = 24.72 W/m^2
Explanation:
E = 96.5 V/m
velocity of light, c = 3 x 10^8 m/s
Let B be the magnetic field.
The relation between the electric field strength and the magnetic field strength is given by
B = E / c = 96.5 / (3 x 10^8) = 32.17 x 10^-8 Tesla
Let u be the energy density.


u = 8.24 x 10^-8 J/m^3
Let Power flow per unit area is
P/A = u x c = 8.24 x 10^-8 x 3 x 10^8 = 24.72 W/m^2
Answer:
209.66 m
Explanation:
Given:
Original length of the spaceship, L = 481 m
Speed of the spaceship, v = 2.70 × 10⁸ m/s
Now,
using the concept of length contraction, we have

where,
L' is the observed length
c is the speed of the light
Thus,
on substituting the respective values, we get

or
L' = 209.66 m
