the photoelectric effect doesn't
Diffraction, Interference etc are the phenomenon which confirm the wave nature of light.!
photoelectric effect
electron diffraction
blackbody radiation
Light is said to be of dual nature so it has particle nature as well as wave nature but there is a difference in waves and electromagnetic waves. so ,as for your question "Is light a electromagnetic wave" the answer is "no"More precisely, if visible is not an electromagnetic wave, the NO part of the electromagnetic spectrum could be considered to be an electromagnetic wave. By any definition of the term, the answer is 'Yes'

Light is transverse in nature.
blackbody radiation
It shows that light behaves as a wave phenomenon. Interference cannot be explained using a particle theory. http://www.physicsclassroom.com/class/waves/Lesson-3/Interference-of-Waves
Light being electromanetic wave is TRANSVERSE in nature.
Light acts like both a particle and a wave.

polarization
No.
Photo electric emission cannot be explained using wave theroy of light. We need quantum theory.
