Step-by-step explanation:
To tell if something is longer than another object is to find the difference between the two objects.
If the difference is < 0, then the object is shorter
If the difference is = 0, then the objects are equal in length
If the difference is > 0, then the object is longer

The difference is > 0, so the wavelength is longer.
