What is the frequency and wavelength of a remote control?
To send a signal to a television, remote controls often use a diode that emits light at around 940 nanometers in wavelength, which falls into the range of near-infrared light. Some digital cameras have filters to block near-infrared light, but most can detect it. It shows up on the screen as if it were visible light.
What blocks remote control?

Is a TV remote control a transmitter or receiver?
A transmitter is often a light emitting diode (LED) which is built into the pointing end of the remote control handset. The infrared light pulses form a pattern unique to that button. The receiver in the device recognizes the pattern and causes the device to respond accordingly.
