Yes. Longitudinal waves can produce standing waves.

electromagnetic waves can travel through vacuum while water waves travel in water.
The direction of electromagnetic waves in media goes all willey nilley.

Optical light waves are "Electromagnetic" waves. The colour seen is dependent on the wavelength of the light. Electromagnetic waves are transverse waves where the oscillation is 90 degrees to the direction of travel (unlike sound waves which are longitudinal).

Electromagnetic waves are waves which can travel through the vacuum of outer space.

The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
Electromagnetic waves are produced by the acceleration of an electric charge. Electromagnetic waves have the same speed in a vacuum (or space). They can slow down and change direction.
Because the theory is that this is what the form is. If it were a longitudinal or compressional form (such as sound) it would need to travel through a medium of some sort to compress the particles of that medium. But electromagnetic radiation can travel even in a vacuum.
We understand that electromagnetic waves have both an electric and a magnetic component. Each component is a wave, and each wave is perpendicular to the other and is in phase. perpendicular to the direction of the wave
