Which object would BEST reflect light from a light bulb?
A
a shiny spoon
B
notebook paper
C
a black sweater
D
a glass of water
Explanation: 

Detailed explanation-1: -The best surfaces for reflecting light are very smooth, such as a glass mirror or polished metal, although almost all surfaces will reflect light to some degree.

Detailed explanation-2: -Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface.

Detailed explanation-3: -While mirrors and other shiny surfaces are the only surfaces that mathematically reflect the images received, this does not mean that they are the only surfaces that reflect light. Think about it this way: in order for us to see anything at all, some light has to hit our eyes. But, not everything emits light directly.

Detailed explanation-4: -Some polished or very smooth objects such as crystals are shiny. Shiny objects reflect most light that hits them in a particular direction. than shiny objects as they absorb some of the light energy. Their surfaces are less smooth than those of shiny objects, so the light they reflect scatters in all directions.

Detailed explanation-5: -Mirrors. Eyes. Water Surface. White Paper. Moonlight. Kitchen Foil. Jewellery and Accessories. Coloured Objects.
