Question
Does one of these visible light waves move faster than the others? Which one is fastest and why?
I think it is C but I am not confident, please help thanks!
Transcribed Image Text:The image displays three sinusoidal waveforms labeled as Wave A, Wave B, and Wave C.
**Wave A:**
- Wave A is a typical sinusoidal wave with several oscillations along its length.
- The wave exhibits moderate frequency, meaning it has a moderate number of cycles occurring in a given time period.
- The amplitude (height of the wave from the center line) is consistent across its cycles.
**Wave B:**
- Wave B also appears as a sinusoidal wave but with a higher frequency than Wave A.
- This means Wave B completes more cycles in the same time period compared to Wave A.
- The amplitude remains similar to that of Wave A, maintaining uniform peaks and troughs.
**Wave C:**
- Wave C is a sinusoidal wave with a lower frequency compared to Wave A.
- It has fewer cycles in the same time period, suggesting slower wave oscillations.
- The amplitude of Wave C is consistent, similar to Waves A and B, though it spans a longer time period for the same cycle.
These waveforms are commonly used to represent different types of periodic functions in physics and engineering, demonstrating various wave properties like frequency and amplitude.
Expert Solution
Step 1
The only electromagnetic waves that we can see are visible light waves. These waves seem to us as rainbow colours. The wavelength of each hue is distinct. The longest wavelength is red, while the shortest wavelength is violet.
Electrical current running through massive broadcast antennas produces relatively lengthy radio waves, but the energy state variations of negatively charged electrons within atoms produce far shorter visible light waves.
