The wavelength of radio waves sent out by an AM station is 600 meters (v = 3.0 x 10^8 m/s). At what frequency is the radio station broadcasting?

500,000 hertz

Explanation:

Wavelength= 600 meters

Velocity(b) = 3 × 10^8

Frequency=?

Therefore the frequency can be calculated as follows

Velocity= frequency × wavelength

Frequency= 3 × 10^8/600

= 500,000 hertz

Hence the frequency is 500,000 hertz

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

the answer for apex is the lowest
