The electromagnetic spectrum encompasses a wide range of wavelengths, from very long radio waves with wavelengths of kilometers to very short gamma rays with wavelengths less than the size of an atomic nucleus. The specific wavelength of electromagnetic radiation depends on the specific type of wave being considered.
What else can I help you with?
What determines how much a wave diffracts when it encounters an opening or a barrier?
The amount of diffraction of a wave when encountering an opening or a barrier is determined by the size of the opening or barrier relative to the wavelength of the wave. Smaller openings or barriers compared to the wavelength lead to more significant diffraction, while larger openings or barriers relative to the wavelength result in less diffraction.
What is a phenomenon that depends on the relative motion of the source and the observer?
The Doppler effect is a phenomenon that depends on the relative motion of the source and the observer. It is the change in frequency or wavelength of a wave in relation to an observer moving relative to the source of the wave.
How does the relative motion between the source of a wave and an observer effect the observation of the wave?
The relative motion between the source of a wave and an observer can affect the observed frequency and wavelength of the wave. If the source and observer are moving towards each other, the observer will perceive a higher frequency and shorter wavelength (Doppler effect). If they are moving away from each other, the observer will perceive a lower frequency and longer wavelength.
Why does diffraction not occur when light passes through a window?
Diffraction does occur when light passes through a window, but the effect is typically minimal due to the small size of the window relative to the wavelength of light. The amount of diffraction is directly proportional to the size of the obstacle or aperture; since windows are relatively small compared to the wavelength of visible light, the diffraction effects are not easily observable.
Is amplitude the apparent change in wavelength?
No, amplitude refers to the maximum displacement of a wave from its rest position. The apparent change in wavelength is known as the Doppler effect, which occurs when there is relative motion between a wave source and an observer.
When was Progress In Electromagnetics Research created?
Progress In Electromagnetics Research was created in 1989.
How do you calculate cumulative frequency and relative frequency?
c=frequency x wavelength

What was the contributions of Hans christian oersted?
he discovered electromagnetics

Is it possible to power a car using electromagnetics?
It is possible to power a car using electromagnetics. The power from an electromagnetic field allows recharging or powering of any device including a car.
What is a radio wave's relative wavelength and frequency compared to other waves in the Electro-Magnetic Spectrum?
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
What is thales experiment?
Thales of miletus (an ancient greek city) experimented with electromagnetics and in that way created what today we know as static electricity. He waved a rod over a cloth with thingees on it and created electromagnetics.
What electromagnetics rays that transfer heat ar called?
It is called radiation.

If a spacecraft is approaching the earth relative to the radio signals it send out the signal received on the earth have?
Shorter wavelength, higher frequency.
