PLEASE PLEASE PLEASE HELP ii. If a radar speed gun operates at a frequency of 3 x 1010 Hz (30 GHz), what
wavelength of electromagnetic radiation does it use? What kind of
electromagnetic wave does the radar gun use? (6 points)

A police car's radar gun emits microwaves with frequency f. 1. =36 GHz. The beam ... waves at f. 2 . • Which frequency is higher, f. 1 or f. 2 ? • Calculate the difference f. 2. – f. 1 . 2. Page 3 ... The Doppler effect for EM waves is derived in ... velocity between source and observer. 4 ... The reflected waves have this shifted.

Explanation:

I enjoy stuff about guns so i hope this helps!

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
