Two microwave signals of nearly equal wavelengths can generate a beat frequency if both are directed onto the same microwave detector. in an experiment, the beat frequency is 140 mhz . one microwave generator is set to emit microwaves with a wavelength of 1.500cm. if the second generator emits the longer wavelength, what is that wavelength?

1.5106 cm

Explanation:

The beat frequency is equal to the absolute value of the difference between the frequencies of the two signals:

using the wave equation, we can re-write each frequency as

where c is the speed of light and is the wavelength. Therefore,

where:

is the beat frequency

is the wavelength of the first generator

is the wavelength of the second generator

We also know that the second generator emits the longer wavelength, so we already know that the term inside the module is positive. Therefore, we can now solve for :

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
