What causes a mirror image?
a mirror... hehe ok ill stop messing around its a light getting reflected off a smooth surface most any smooth surface will reflect something the only thing that can over come a mirrors reflection is light itself and the angle at which it is reflected off (the secret to a one way mirror)
How does reflection change a wave?
Reflection can have an effect on a wave in that heat loss occurs when light energy is reflected as opposed to being absorbed by the surface of the wave. This reflection would result in a cooling of surface temperature. An example would be a dirty water's propensity to absorb light energy more so than a clear water which would have less insulating capacity due to less density and a finer quality of reflection. The transparency that accompanies better reflection results in a cooler surface temperature which can modify the amount of energy over a period of time so that the denser unclear water causes more absorption of energy and potentially smaller waves while the clearer more reflective water allows less drag on the light energy that is acting on the system.
What is a surface from which light will bounce back?
it is the one and only thing that causes the light to bounce back and it is known as the one and only thing.......... Actually not thing but yes............., no................ Leave it. The thing is REFLECTION. Ya, my dear and dearest friends it is REFLECTION.
What is the reflection?
Well reflection is just basically light bouncing off an object. An important law of reflection is that: "At whatever angle the light enters the mirror, it will leave the mirror at the same angle". So if you shoot light at a mirror at an initial angle of 65 degrees, it will reflect at a final angle of 65 degrees also.
What happens in absorption transmission and scattering of light?
Reflection is the process by which electromagnetic radiation is returned either at the boundary between two media (surface reflection) or at the interior of a medium (volume reflection), whereas transmission is the passage of electromagnetic radiation through a medium. Both processes can be accompanied by diffusion (also called scattering), which is the process of deflecting a unidirectional beam into many directions. In this case, we speak about diffuse reflection and diffuse transmission (Fig. II.14). When no diffusion occurs, reflection or transmission of an unidirectional beam results in an unidirectional beam according to the laws of geometrical optics (Fig. II.15). In this case, we speak about regular reflection (or specular reflection) and regular transmission(or direct transmission). Reflection, transmission and scattering leave the frequency of the radiation unchanged. Exception: The Doppler effect causes a change in frequency when the reflecting material or surface is in motion.Absorptionis the transformation of radiant power to another type of energy, usually heat, by interaction with matter.Fig. II.14 - a-c: Direct, mixed and diffuse reflection d-f: direct, mixed and diffuse transmissionFig. II.15 - When directly reflected or directly transmitted, an unidirectional beam follows the laws of geometrical optics: direct reflection (left): ain = aout, direct transmission (right): n1 · sin(ain) = n2 · sin(aout) with n1 and n2 denoting the respective medium´s index of refractionII.8.a. Reflectance r, Transmittance t, and AbsorptanceaIn general, reflection, transmission and absorption depend on the wavelength of the affected radiation. Thus, these three processes can either be quantified for monochromatic radiation (in this case, the adjective "spectral" is added to the respective quantity) or for a certain kind of polychromatic radiation. For the latter, the spectral distribution of the incident radiation has to be specified. In addition, reflectance, transmittance and absorptance might also depend on polarization and geometric distribution of the incident radiation, which therefore also have to be specified.Thereflectance r is defined by the ratio of reflected radiant power to incident radiant power. For a certain area element dA of the reflecting surface, the (differential) incident radiant power is given by the surface's irradiance Ee, multiplied with the size of the surface element, thusdFe,incident = Ee dAand the (differential) reflected radiant power is given by the exitance Me, multiplied with the size of the surface element:dFe,reflected = Me dAThus,orMe = r EeTotal reflectance is further subdivided in regular reflectance rr and diffuse reflectancerd, which are given by the ratios of regularly (or specularly) reflected radiant power and diffusely reflected radiant power to incident radiant power. From this definition, it is obvious thatr = rr + rdThe transmittance t of a medium is defined by the ratio of transmitted radiant power to incident radiant power. Total transmittance is further subdivided in regular transmittance tr and diffuse transmittance td, which are given by the ratios of regularly (or directly) transmitted radiant power and diffusely transmitted radiant power to incident radiant power.Again,t = tr + tdThe absorptance a of a medium is defined by the ratio of absorbed radiant power to incident radiant power.Being defined as ratios of radiant power values, reflectance, transmittance and absorptance are dimensionless.Quantities such as reflectance and transmittance are used to describe the optical properties of materials. The quantities can apply to either complex radiation or to monochromatic radiation.The optical properties of materials are not a constant since they are dependent on many parameters such as:• thickness of the sample• surface conditions• angle of incidence• temperature• the spectral composition of the radiation (CIE standard illuminants A, B, C, D65 and other illuminants D)• polarization effectsThe measurement of optical properties of materials using integrating spheres is described in DIN 5036-3 and CIE 130-1998.Descriptions of the principle measurements are presented in paragraph III.1.f below.II.8.b. Radiance coefficient qe, Bidirectional reflectance distribution function (BRDF)The radiance coefficient qe characterizes the directional distribution of diffusely reflected radiation. In detail, the radiance coefficient depends on the direction of the reflected beam and is defined by the ratio of the radiance reflected in this direction to the total incident irradiance. In general, the reflected radiance is not independent from the directional distribution of the incident radiation, which thus has to be specified.In the USA, the concept of Bidirectional reflectance distribution function BRDF is similar to the radiance coefficient. The only difference is that the BRDF is a function of the directions of the incident and the reflected beam (Fig. ). In detail, the (differential) irradiance dEe impinging from a certain direction causes the reflected radiance dLe in another direction, which is given bydLe = BRDF · dEeThis BRDF depends on more arguments than the radiance coefficient. However, its advantage is the simultaneous description of the material's reflection properties for all possible directional distributions of incident radiation, whereas the radiance coefficient generally is valid for just one specific directional distribution of incident radiation.The unit of radiance coefficient and BRDF is 1/steradian. The BRDF is often abbreviated by the Greek letter ñ, which bears the danger of mixing the BRDF up with reflectance (see foregoing paragraph).Fig. II.16 - Geometry used for the definition of the bidirectional reflectance distribution function (BRDF). The BRDF depends on the directions of incident and reflected radiation, which are given by the angles Ji and Jr, which are measured relative to the reflecting surface's normal, and the azimuth angles ji and jr, which are measured in the plane of the reflecting surface.
What is an angle reflection?
The angle formed by a reflected ray and a perpendicular to the surface at the point of reflection. (Physics / General Physics) the angle that a beam of reflected radiation makes with the normal to a surface at the point of reflection Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. In acoustics, reflection causes echoes and is used in sonar. In geology, it is important in the study of seismic waves. Reflection is observed with surface waves in bodies of water. Reflection is observed with many types of electromagnetic wave, besides visible light. Reflection of VHF and higher frequencies is important for radio transmission and for radar. Even hard X-rays and gamma rays can be reflected at shallow angles with special "grazing" mirrors >NMMS< I Love GOD

What happens when the sun's rays hit the Earth's surface?
Radiant energy will either be reflected or absorbed by a surface. The usual rule regarding this reflection depends on the color of the object and the color of the light. For example, a red object only reflects red light, and absorbs the rest. A blue object only reflects blue light, and absorbs the rest. This goes for all of the colors. When radiant energy is absorbed, the object will heat up. Hope this helps!
