What happens if an infrared remote control is pointing and coming at your eye really fast while transmitting... would the frequency of the em waves increase? If so, how fast would it need to be traveling in order to appear red?
:grumpy: Hey! I wanted to make a Doppler roller-coaster, with humans having enough speed to see the same colors through all the trip while the light itself did change. :grumpy:collinsmark said:Seriously though, the angriest of all angriest boyfiends/girlfriends could not cause enough Doppler shift to cause the infrared light to appear visible simply by hurling it at your face, without some sort of mechanized launching apparatus such as a highly sophisticated rail-gun or some such, which is beyond our present technology.
Infrared remote controls work by using infrared light to transmit signals between the remote and the device it is controlling. When a button is pressed on the remote, it sends a coded signal in the form of infrared light pulses to the receiver on the device. The receiver then decodes the signal and carries out the corresponding command.
Infrared light travels at the speed of light, which is approximately 299,792,458 meters per second. This speed is necessary for the remote control to send and receive signals quickly and efficiently.
The speed of infrared light does not need to be altered for the remote control to work. As mentioned, infrared light already travels at the speed of light, which is fast enough for the remote to send and receive signals in real-time.
No, the speed of infrared light does not affect the functionality of the remote control. As long as the remote and the device are within range and have a clear line of sight, the speed of infrared light will not impact the performance of the remote.
The speed of infrared light has no limitations for remote controls, as it is already traveling at the speed of light. However, the range and line of sight between the remote and the device can affect the speed at which the signal is received, leading to delays or malfunctioning of the remote control.
