Which color wave has the largest frequency?
n
purple
red
blue
orange
green

purple

Explanation:

There is an inverse relation between frequency and wavelength :

Where is the speed of light in vacuum

This means:

If increases decreases and if decreases increases.

In other words, the color wave with the largest frequency is the one with the lowest wavelength.

In this sense, the wavelength for each color is:

As we can see, purple has the smallest wavelength, hence the largest frequency.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
