Light & Refraction: Wavelengths & Frequency Ratios

[stickplot]

Ok so I am not sure how to do this problem the only equation i am familiar with that might have to do with it but I am not so sure it is used on this problem the equation is dsin(-)=wavelength

the question is

2.Compare the wavelength or frequency range of the visible light our eyes can see to the range of radio light. Red wavelength = 700 nanometers, frequency = 4.29 x 1014 Hz Violet wavelength = 400 nanometers, frequency = 7.5 x 1014 Hz Radio (AM radio) wavelength = 555 m, frequency = 5.4 x 105 Hz (540 kHz) Microwave (microwave oven) wavelength = 12 cm, frequency = 2.5 x 109 Hz What is the ratio of red to violet light compared to the ratio of AM radio to microwaves? Give the ratios for either wavelength or frequency.

thank you!

It's just a ratio problem. How does the ratio (700 nanometers)/(400 nanometers) compare to the ratio of (555 m)/(12 cm)? That's all.

o ok thank you
