The constituents of mantle are 44% oxygen, 22% magnesium and 21% silicon. There is some amount of iron, aluminium, potassium and sodium in mantle.

The light transmitted by a filter is <em>less bright </em>than the light that hits it.

A filter only absorbs/removes part of the light that hits it. That means it removes some energy from the incident light. The remaining light carries less energy, so it must be less bright.
