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 :

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.
