(B) The wavelength of red light is approximately $700 \, 	ext{nm}$ $(620-750 \, 	ext{nm})$.The wavelength of blue light is approximately $400 \, 	ext{nm}$ $(400-450 \, 	ext{nm})$.The ratio of the wavelength of red light to blue light is $\frac{700 \, 	ext{nm}}{400 \, 	ext{nm}} = 1.75 \approx 1.8$.Therefore, the wavelength of red light is approximately $1.8$ times the wavelength of blue light.

How many times is the wavelength of red light compared to the wavelength of blue light?
