Suppose there is a 50 watt infrared bulb and a 50 watt UV bulb. Do they emit light of the same energy?

Why are red and blue light refracted differently if they travel at the same speed in the same medium?

What is the origin of the Sun light?

What exactly was the "classical model" of black-body radiation, and what assumption about it made it wrong?

How do virtual images make any sense?

Is spin necessary for electromagnetism?

Are magnetic field and electric field perpendicular is spherical waves?

Can X-ray diffraction be applied to liquids, gasses or non-crystalline materials?

Is number of photons undefined for a classical EM wave?

Do photons take all paths or not?
