The earths surface transfers heat to the atmosphere primarily by?
The Earth's surface transfers heat to the atmosphere primarily by convection and radiation. As the surface heats up, air in contact with the surface warms up and rises, creating vertical currents of warm air. At the same time, the Earth's surface emits radiation in the form of heat, which is absorbed by the atmosphere.
What is a good reflector of light?
A mirror is a good reflector of light because it has a smooth and highly reflective surface that bounces light rays off at equal angles, resulting in a clear reflection.
Does the moon have radiation on the surface?
Yes, the moon's surface is exposed to cosmic radiation from space due to its lack of atmosphere to shield it. The radiation levels on the moon's surface are higher than on Earth, but astronauts are protected by their spacesuits and spacecraft when exploring the lunar surface.
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as which type of electromagnetic radiation?
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as infrared radiation. This process helps to maintain Earth's energy balance and regulate its temperature.
Surface that curves outward and reflects and spreads light?
Convex surface. It is curved outward and acts as a reflector, spreading light in various directions. This type of surface is commonly used in mirrors and lenses to focus or diverge light rays.
What kind a surface is the best reflector of sound?
The best reflector for sound will be massive, rigid, and with a smooth surface.
Which is a better reflector of light- a black surface or a white surface?
which is a better reflector of light-a black surface or a white surface
Is earth is a good reflector of heat?
Yes, Earth is a good reflector of heat through a process known as albedo, which is the reflection of sunlight and heat off its surface. The Earth's surface reflects about 30% of incoming solar radiation back into space, helping to regulate the planet's temperature.
Name the type of a reflector with a smooth surface?
A reflector with a smooth surface is typically known as a specular reflector. This type of reflector reflects light in a single, predictable direction without scattering or diffusing it.
Name a type of reflector with a smooth surface?
A parabolic reflector is a type of reflector with a smooth surface that can collect and reflect light or sound waves to a single focal point.

What uses a wire mesh as a reflector to collect radiation from space?
A radio telescope uses a wire mesh as a reflector to collect radiation from space. The mesh acts as a surface to focus electromagnetic waves, such as radio waves, enabling astronomers to study celestial objects and phenomena. The collected signals are then directed to a receiver for analysis and interpretation.
Which type of surface would most likely the best reflector of electro magnetic energy?
A smooth and polished metallic surface, such as silver or aluminum, would be the best reflector of electromagnetic energy. These surfaces have high reflectivity due to their free electron density, allowing them to efficiently reflect a wide range of electromagnetic frequencies.
What surface is the best at emitting radiation?
Black surfaces are typically the best at emitting radiation, as they absorb more radiation and therefore emit more as well. This is known as blackbody radiation.
Has a reflecting surface that curves outward?
A convex reflector.
What is the emissivity of an ideal reflector?
The emissivity of an ideal reflector is 0, meaning it reflects all incoming radiation without emitting any.
What is difference between emissivity and reflectance?
Emissivity refers to the efficiency with which an object emits thermal radiation, ranging from 0 to 1. Reflectance, on the other hand, pertains to the ability of a surface to reflect light or radiation, also ranging from 0 to 1. In essence, emissivity relates to the emission of radiation from an object, while reflectance involves the reflection of incident light.
