Light is described as having wavelength. I can somewhat understand this in connection with for example the double slit experiment, that photons interact spatially in a wave like manner.
But can the wavelength of light be described in a way which more intuitively relates to the waves of sound or oceans? Does "the length" have a specific orientation relative to the path of light? Doppler shifts seem to indicate that the wavelength is measured in the direction of light's movement, the speed stretches it out. But the double slit experiment, and the shapes of antennas, seem to indicate that the wavelength is meassured perpendicular to light's movement.
How large is a photon and what shape does it have in terms of its "length"?
