Question

Two rays of light have different colors (blue and green), and both are equally bright compared to the other. Indicate whether each property is the same or different when describing the wavelength, and indicate whether the property is larger for blue or green.

Answer 1

The frequency and wavelength of blue and green light are compared in different scenarios. The wavelength of blue light is shorter than green light when they have the same frequency. The wavelength of green light is longer than blue light when the frequency of green light is lower.

Step-by-step explanation:

In the given scenarios, we are comparing blue and green light. Let's analyze each case:

(e) The frequency of green light is the same as the frequency of blue light and the wavelength of green light is shorter than the wavelength of blue light. When the frequency is the same, the wavelength is inversely proportional to the frequency. This means that a higher frequency corresponds to a shorter wavelength. Therefore, the wavelength of blue light is shorter than the wavelength of green light in this scenario.

(d) The frequency of green light is lower than the frequency of blue light and the wavelength of green light is longer than the wavelength of blue light. In this case, since the frequency of green light is lower than that of blue light, the wavelength of green light would indeed be longer compared to the wavelength of blue light.

(b) The frequency of green light is higher than the frequency of blue light and the wavelength of green light is shorter than the wavelength of blue light. Here, as the frequency of green light is higher than that of blue light, the wavelength of green light is shorter compared to the wavelength of blue light.
