What is the wavelength for radio waves with frequency 3x10^9

Mathematics
1 answer:
lozanna [386]3 years ago

Answer:

0.1 meters

Step-by-step explanation:

For an electromagnetic wave, the relationship between wavelength λ, frequency ν, and the speed of light c is given by:

c=\lambda \nu

where c=3*10^8m/s.

In our case of the radio waves \nu=3*10^8

therefore the wavelength λ is:

\lambda=\frac{c}{\nu} =\frac{3*10^8}{3*10^9} =0.1m.  

Therefore the wavelength of the radio waves is 0.1 meters.

Find the area of the circle.. PLEASE HELP
Leno4ka [110]

Answer:

The area is 154 cm²

Step-by-step explanation:

Since the formula for the area of a circle is pi times the radius squared, divide the diameter in half to get the radius (7). Then, square the radius (49). Next, multiply that by pi (153.938). After that round to the nearest whole number (154). Hope that helps!
