Why does wavelength affect diffraction? For example, red light with a longer wavelength can easily bend around objects. I'm assuming that because of the characteristic longer wavelength, it can just easily bend (flex) as opposed to blue light with would have difficulty becuase of shorter wavelengths. I have this mental picture of red light like a piece of string, where the crests and troughs give the string an apparent wave appearance. Because the crests [and troughs] are further away from each other, the string can easily bend around objects. Is this the right view point? --thanks.
