Physics Review Question Unit: Waves Year: 1994 Question#: 54 Question: As the color of light changes from red to yellow, the frequency of the light (1 ) increases (2 ) decreases (3 ) remains the same What is this question really asking? Explanation by: Megan C. [ Return to question menu ] Answer 1 Increases CORRECT Yellow light will have a higher frequency than red light. Because moving toward violet increases the frequency, red light will have a lower frequency than yellow light. return to top Answer 2 Decreases INCORRECT In the visible spectrum, red light has the lowest frequency. Moving to the right and toward violet increases the frequency, but red has the lowest frequency so if the frequency decreases the light will become infared light. return to top Answer 3 Remains the same INCORRECT If the frequency were to remain the same, the color of the light would not change. return to top What's this question really asking? This question is asking if you know how the frequencies act in the electromagnetic spectrum in relation to color. return to top |
