What are the different ranges of frequencies that radar can operate and give their applications?

Most radars, in practice, operate between 400 MHz to 36 GHz ; however, there are some notable exceptions. The optical and radio portions of the electromagnetic spectrum occupy positions coincidental with two important transparent bands in the Earth’s atmosphere and ionosphere.

RADAR is an electromagnetic system for the detection and location of target objects such as aircraft, ships, spacecraft, vehicles, people, and the natural environment which can reflect a signal back . It uses electromagnetic radio waves to determine the angle, range, or velocity of objects.
