Blue light has a shorter wavelength than yellow light. which color has the higher frequency. o blue o yellow o they have the same frequency

Blue light has the higher frequency.

Explanation:

Remember that the relation between wavelength and frequency for any electromagnetic wave in the vacuum is

where is the speed of light in the vacuum. As you can see, the relation between frequency and wavelength is inversely proportional. The higher is the wavelength, the lower is the frequency.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
