Create a 15-element ULA of isotropic antenna with elements spaced one-half wavelength apart. Plot the directivity of the array at 20 GHz. Then, find the mainlobe, sidelobe, and backlobe directions of the array pattern. Get fc = 20.0e9; c = physconst('Lightspeed'); lam = c/fc; angs...
What is the wave speed? A wave has an amplitude of 0.25 m, a wavelength of 0.68 m and a frequency of 3.2 Hz. Find it's velocity. A harmonic wave travels with a speed of 200 m/s and has a wavelength of 0.800 m. What is the period of the wave? If a wave ...
Each color has a different wavelength (波长). Blue has one of the shortest wavelengths.Earth’s atmosphere (大气层) is full of tiny air molecules (分子). When light hits them, it gets scattered (散射) around. Light with shorter wavelength bounces like a ping-pong ball until it reaches ...
Newton’s first law, often called the law of inertia, states that an object at rest will stay at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force.Centripetal forceis an example of this. ...
The energy for n number of photons is mathematically calculated using the product of the number of the photon, plank constant, and the frequency. As we know that the frequency is the ratio of speed and wavelength, so the energy of photon varies inversely with the wavelength as: ...
In summary: I just provided a summary of the conversation.In summary, Dave found that by using the highest frequency, he was able to find f0 by finding the average between the two frequencies. Then, he used the same method to find Vsource. However, when he tried to do the ...
IR remote conrols use light with a wavelength of approximately 900 nm. Light of this wavelength is invisible to humans but can be detected by black and white CCD cam- eras. The IR pulses that are emitted by the remote control can be seen as a flashing light on the video monitor. This...
