An outdoor wi-fi unit for a picnic area has a 110 mw output and a range of about 38 m. what output power (in mw) would reduce its range to 18 m for use with the same devices as before? assume there are no obstacles in the way and that microwaves into the ground are simply absorbed.

The output power is 24.68 mW.

Explanation:

Given that,

Power = 110 mW

Range = 38 m

Reduced range = 18 m

We need to calculate the power

Using formula of intensity

As intensity is constant

So,

Put the value into the formula

Hence, The output power is 24.68 mW.

what question you dont ask a question

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
