As you drive away from a radio transmitter, the radio signal you receive from the station is shifted to longer wavelengths.
mylen [45]

Answer:

True

Explanation:

{Apparent}.wavelength = (True.wavelength)(1 +\frac{recession.velocity}{wave.speed})

As one drive away from the radio station, the recession velocity increases and causes the apparent wavelength to increase accordingly, which in turn causes the True wavelength received from the radio station to increase as well because of their direct relationship as shown in the equation above.

At a rock concert, a dB meter registered 131 dB when placed 2.6 m in front of a loudspeaker on the stage. The intensity of the r
Pavlova-9 [17]

Answer:

Explanation:

A) 131 dB = 10*log(I / 1e-12W/m²)

where I is the intensity at 2.6 m away.

13.1 = log(I / 1e-12W/m²

1.25e13= I / 1e-12W/m²

I = 1.25 x10^1W/m²

power = intensity * area

P = I * A = 12.5W/m² * 4π(2.6m)² =1061 W ◄

B) 86 dB = 10*log(I / 1e-12W/m²)

8.6 = log(I / 1e-12W/m²)

3.98e8 = I / 1e-12W/m²

I = 3.98e-4 W/m²

area A = P / I = 1061W / 3.98e-4W/m² = 2.66e6 m²

A = 4πr²

2.66e6 m² = 4πr²

r = 14.5m ◄

What kind of motion for a star does not produce a Doppler effect? Explain.
-BARSIC- [3]

Answer:

 Transverse motion does not produced a doppler effect for a star. As, the doppler effect are occurred when the object are emitting light either in the direction towards the observer or moving away. The various astronomical objects are moving and the observer observed the blue wavelength of the light.

Doppler effect in the star is the process when the observer moves towards the star then it seems like the star move towards the observer.
