compared to the period of a wave of red light the period of green light is...
A)less
B)greater
C)the same
D)none of the above
It's snicker-worthy how light just can't stick to the same script, isn't it? The period of green light is actually the same as the period of red light, two hilarious peas in a pod. So the answer is C) the same. Keep those waves wavy, my friend!
The correct answer is C) the same.
The period of a wave represents the time it takes for one complete cycle. For electromagnetic waves, including light waves, the period is determined by the frequency. Red light and green light are both part of the visible light spectrum, and they travel at the same speed. Therefore, the period of a wave of red light is the same as the period of a wave of green light.
To compare the periods of two waves, we need to understand what period means in the context of waves. The period of a wave refers to the time it takes for one complete cycle of the wave to occur. It is measured in seconds (s).
Now to determine if the period of green light is greater, less, or the same as the period of red light, we need to consider their respective wavelengths. Wavelength refers to the distance between two consecutive points on a wave, such as two peaks or two troughs.
In general, red light has a longer wavelength compared to green light. This means that for each complete cycle of a red light wave, it covers a greater distance than a green light wave.
Since the period of a wave is determined by the time it takes to complete one cycle, and red light covers a longer distance in one cycle, it can be concluded that the period of red light is greater than the period of green light.
Therefore, the correct answer is B) greater.
The wavelength of green is shorter. What does that imply about the period?
Wavelength/Period = speed of light
