All objects on Earth emit IR radiation, or heat, which can be detected by electronic sensors, such as those used in night-vision goggles and infrared cameras. A simple example of such a sensor is the bolometer, which consists of a telescope with a temperature-sensitive resistor, or thermistor, at its focal point

That means that light exhibits some of the phenomena that are typical for waves, such as diffraction and interference.

While there are no true voltage sources, some reasonable approximations of them exist:DC, any type of batteryDC, voltage regulated power supplyAC, wall outletAC, true sine-wave UPSAC, variable frequency sine-wave signal generatoretc.
Examples of wave energy include ocean waves, tidal currents, and underwater currents. These natural sources of energy can be harnessed to generate electricity using technologies such as wave energy converters and tidal turbines.
The typical amplitude of a P wave on an electrocardiogram (ECG) is usually less than 0.25 mV (2.5 mm).
A P wave has a frequency range of 0.5 to 20 Hz, with typical frequencies falling between 2 to 8 Hz.

To determine how long it takes a wave to travel 5000 km, you need to know the wave's speed. For example, if the wave travels at a speed of 300 m/s (typical for sound in air), it would take approximately 16.67 hours to cover that distance. If the wave travels faster, say at 1500 m/s (typical for sound in water), it would take about 3.47 hours. Therefore, the time depends on the specific speed of the wave in question.
