<span><span>-When sunlight strikes a falling drop of water it is refracted, changed indirection, by the surface of the water.</span>
The light continues into the drop and is reflected from the back of the drop to the front. When the beam hits the front it is refracted again and emerges from the drop as the color spectrum that we see in a rainbow.<span>-The water drop acts like a prism to seperate the light into its different wave lengths.</span></span>
Answer:
<em>The signal x[n] = 16000 samples</em>
Explanation:
From the question,
S = x/t ................................... Equation 1
making x the subject of the equation
x = St .................................. Equation 2
Where S = sample rate ( samples per seconds), x = signal (samples), t = time ( seconds)
<em>Given: S = 8000 samples, t = 2 seconds.</em>
<em>Substituting these values into equation Equation 2</em>
<em>x = 8000×2</em>
<em>x = 16000 samples.</em>
<em>Thus the signal x[n] = 16000 samples</em>
