SpletThis is because optics deals with the behavior of light, and light is one example of an electromagnetic wave. ... It turns out that for an electromagnetic wave, the energy associated with the electric field is equal to the energy associated with the magnetic field, so the energy density can be written in terms of just one or the other: Splet≈ 1.538. ; Where c is the speed of light in vacuum. (b) Given that the wavelength (λ) = 30cm = 0.3m.; and the refractive index of the quartz block nq = √ K = √ 4.3. Now the frequency …

SpletThose collisions produce tiny flashes that fill the sky with colourful light. As billions of flashes occur in sequence, the auroras appear to move or "dance" in the sky. Earth's magnetic field steers the charged particles towards the poles. The shape of Earth's magnetic field creates two auroral ovals above the North and South Magnetic Poles. SpletLight is an electromagnetic radiation, an electric field that oscillates in both time and space along with a corresponding orthogonal magnetic field that oscillates with the same spatial and temporal periodicity. This was first … cloud streaming playstation on pc
