Which one of the following reflects back more sunlight as compared to other?
The correct answer is Land covered with fresh snow. Land covered with fresh snow: Fresh snow and ice are believed to reflect approx. 80-85% of the sunlight.
Does snow reflect sunlight?
Snow is highly reflective. On a sunny day, clean fresh snow can reflect up to 90% of UV radiation. This means that you can be exposed to almost a double dose of UV – directly from the sun and bouncing off snow-covered surfaces.
What is the most reflective surface on Earth?
snow
In fact, snow is the most reflective natural surface on Earth.
Is water or ice more reflective?
In fact ice is slightly less reflective than water. The reflectivity is related to the refractive index (in a rather complicated way) and the refractive index of ice is 1.31 while the refractive index of water is 1.33. The slightly lower refractive index of ice will cause a slightly lower reflectivity.
Does water reflect light?
Water and glass not only reflect but also refract light. This means that as a light beam enters water or glass, the light bends.
What is the best reflective surface?
The shiny side of aluminum foil is the best reflective material in our test and it’s also cheap and relatively easy to work with.
What material reflects most light?
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.
What material is most reflective?
Silver is the most talked about when it comes to high reflectivity value. Silver mirrors have been manufactured since a long time and used in the household but here we do not only talk about the reflection of visible wavelengths of the electromagnetic spectrum but also UV and IR wavelengths.
Why is snow white but water clear?
For snow to be white, it means that it must be reflecting all the different colors of light equally. For ice to be clear, it is transmitting all the colors of light equally and not reflecting them back to your eye.
Does ocean reflect or absorb sunlight?
Almost all sunlight that enters the ocean is absorbed, except very close to the coast. The red, yellow, and green wavelengths of sunlight are absorbed by water molecules in the ocean.
Does water absorb sunlight?
Water absorbs almost all of the infrared energy from sunlight within 10 centimeters of the surface.
Why is the sun brighter at the beach?
At the coast the horizon facing the ocean is unobstructed, so a larger part of the sky is visible than inland, where trees, buildings, etc., block the view of the horizon. Also, the horizon sky is brighter than the overhead sky. At or near the horizon the sky appears lighter blue than at the zenith, or even whitish.
Does wood reflect light?
Wood, concrete and paper don’t reflect, partly because their surfaces are not very smooth, and he light that hits the surface of these materials is scattered all over. A smooth sheet of paper (a glossy magazine cover) will reflect.
What is reflected sunlight called?
Earth’s ability to reflect the Sun’s light, called albedo, is influenced by the color, type and texture of surfaces ranging from snow, vegetation and urban areas.
What color is most reflective?
Pure white
Pure white, being the most reflective color, is at the other end of the scale at 100 because it doesn’t absorb light or warmth. Colors that fall below 50 on the LRV scale will absorb more light than they reflect.
What is the most reflective mirror?
The world’s most reflective mirrors, which reflect 99.9999% of incident light, were developed by a French laboratory. Discover the manufacturing secrets of these essential components of gravitational wave detectors.
Can aluminium foil reflect sunlight?
Aluminum foil is said to be not absorbing light at all. It reflects light.
What is the best light reflector?

What material can reflect sunlight?
Light reflecting factor materials.
| Material | Reflection Factor (%) |
|---|---|
| Aluminum coatings, matte | 55 – 56 |
| Aluminum, anodized, matte | 80 – 85 |
| Aluminum, matte | 55 – 75 |
| Aluminum, polished | 65 – 75 |
What material absorbs sunlight the best?
Non-metallic materials such as brick stone and brick are good absorbers of solar energy, especially if they have dark coloring. Plastics and wood may make good energy absorbers, but many types are not suitable for solar applications because most plastics have relatively low melting points and wood may catch fire.
