of resolving wavelengths as close as 10−3nanometre, while modern laser techniques can resolve optical wavelengths separated by less than 10−10nanometre. The frequency with which the electromagnetic wave oscillates is also used to characterize the radiation. The product of the frequency (ν) and...
single colour. laser light is directional laser light is highly directional. laser light is coherent laser light is coherent because the wavelengths of the laser light are in phase in space and time. uses of led leds find applications in various fields, including optical communication, alarm and...
Application cases in millimeter wave radar in the field of the smart home are also increasing. With the acceleration of the aging process, millimeter wave radar and wisdom endow have evolved a lot of new use of a falling alarm, sleep monitoring, etc. Millimeter waves can also detect subtle ...
