Question

Two lasers produce light with the same intensity but different colors. Laser Y produces yellow light (f = 5.17 x 10¹⁴ Hz), and laser B produces blue light (f = 6.40 x 10¹⁴ Hz). Which statement best describes the light from the two lasers?

1) The yellow light has a higher frequency than the blue light.
2) The blue light has a higher frequency than the yellow light.
3) The yellow light has a higher wavelength than the blue light.
4) The blue light has a higher wavelength than the yellow light.

Answer 1

The correct statements are that the blue light from laser B has a higher frequency than the yellow light from laser Y, and the yellow light has a higher wavelength than the blue light.

Step-by-step explanation:

Comparing the light from two lasers, Laser Y that produces yellow light with a frequency of 5.17 x 10¹⁴ Hz, and Laser B that produces blue light with a frequency of 6.40 x 10¹⁴ Hz, we can determine which statements are accurate. We know that in the visible spectrum, blue light has a higher frequency than yellow light.

The correct statement describing the light from the two lasers is: 2) The blue light has a higher frequency than the yellow light. Moreover, since the frequency and wavelength of light are inversely related (as one increases, the other decreases), we can also conclude that 3) The yellow light has a higher wavelength than the blue light.

These statements align with the general properties of visible light, where red light has the lowest frequencies and longest wavelengths, while violet light has the highest frequencies and shortest wavelengths.
