Astronauts traveling toward Earth in a fastmoving
spacecraft receive a radio signal from an
antenna on Earth. Compared to the frequency
and wavelength of the radio signal emitted from
the antenna, the radio signal received by the
astronauts has a
(1) lower frequency and a shorter wavelength
(2) lower frequency and a longer wavelength
(3) higher frequency and a shorter wavelength
(4) higher frequency and a longer wavelength


Sagot :

Compared to the frequency and wavelength of the radio signal emitted from
the antenna, the radio signal received by the astronauts has a (1) lower frequency and a shorter wavelength.

Answer:

3) Higher frequency and a shorter wavelength

Explanation:

The Doppler Effect occurs when the distance between the wave source and the observer is changing. As the astronauts move toward the source of the radio waves, the radio waves will reach them at a faster rate. The perceived frequency will be higher and the wavelength shorter.
