Why do we need shiny surface?

We need a shiny surface for reflection because the shiny surface of the plane mirror gives us the maximum reflection of light. This helps in forming a bright image. That is why mirror reflects most of the light falling on it. Hence for reflection, shiny surfaces are required.

Are shiny surfaces good at reflecting light?

When light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it. Smooth, shiny surfaces such as mirrors and polished metals reflect light well.

What are the examples of shiny objects?

Shiny items for example:

• tinsel.
• foil wrapping paper.
• ornaments.
• metallic ribbon.
• bells.
• metallic Christmas cards.
• glittery items.

Why are some surfaces reflective?

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. For a rough surface, reflected light rays scatter in all directions.

Which surfaces are better reflectors?

Smooth, light coloured, or shiny surfaces like glass, water and metal are excellent reflectors. All the light that hits them bounces back off.

What is something shiny?

Shiny describes something with a smooth, glossy surface. If you want to see your reflection in the glass table, you’ll have to polish it to keep it shiny. Something shiny has a shine, a brightness that comes from reflecting light. Are you into shiny new cars, or shiny diamonds?

What is a shiny object?

Shiny objects are things that look good and exciting, but are really distractions at the end of the day. There are many new products these days that look promising but don’t add value to your work and life.

Why do materials reflect light?

Rather the electrons of atoms on the material’s surface vibrate for short periods of time and then reemit the energy as a reflected light wave. Such frequencies of light are said to be reflected.

What things reflect?

Light reflects off objects and allows us to see. Some objects reflect light very well, like mirrors and white papers. Other objects, like brown construction paper, do not reflect as much light. Water is also good at reflecting light off its surface.

What are good and bad reflectors of sound?

Answer: The objects which reflect sound and have a hard and smooth surface are good reflectors of sound. The objects which do not reflect sound and are soft and porous are bad reflectors of sound.

What does shiny surface mean?

Shiny describes something with a smooth, glossy surface. If you want to see your reflection in the glass table, you’ll have to polish it to keep it shiny. Something shiny has a shine, a brightness that comes from reflecting light.

Why do things look shiny when they reflect light?

If the light starts out in the dense material (like water or glass) and hits the surface with air, if the angle is steep enough so that the law of refraction cannot be satisfied, then all of the light will bounce back into the water or glass, in a process called “total internal reflection”, making that surface look shiny too.

Why do reflective surfaces reflect light?

A new concept that I learnt says that the reflection is due to the scattering of light by electrons in the material. I’ve got my head around this yet something that bothers me is how do shiny surfaces like a mirror or reflective surface like silver or platnum reflect almost all of the light that it receives and yet certain other metals don’t.

Are shiny materials good reflectors of light?

Yes, shiny materials are good reflectors of visible light, one of many kinds of radiation. They may not be such good reflectors of other kinds of radiation, like x-rays, for example, which are just like light except they have higher frequencies.

How can a material be shiny?

There’s another way a material can be shiny. If a material is transparent, but has a different index of refraction than the air, then light rays will bend when they strike the surface of the material. Some, but not all, will also be reflected from the surface at the same angle of reflection as if the material had been made out of metal.
