What are the wavelength and frequency of the reflected light? For what angle of incidence is the reflected ray normal to the incident ray? The reflected wavelength is. What are the wavelength and frequency of reflected light. Ligtht falls on a plane reflecting surface. For what angler of incidence is the reflected ray normal to the incident ray.

A light of wavelength 5000 angstrom

What are the wavelength and frequency of the reflected light? For what angle of incidence is the reflected ray normal to the incident ray? The wavelength and frequency of incident light is the same as that of reflected ray. When reflected ray is normal to incident ray, the sum of the angle of incidence, ang. What is the force between two small charged spheres having charges of 2 x 10 -7 C and 3 x 10 -7 C placed 30 cm apart in air? Calculate the linear charge density. A pF capacitor is charged by a V supply. It is then disconnected from the supply and is connected to another uncharged pF capacitor. How much electrostatic energy is lost in the process? What will be the capacitance if the distance between the plates is reduced by half, and the space between them is filled with a substance of dielectric constant 6? Calculate the potential at the centre of the hexagon.

The number of incident photons N per second per square metre is therefore:. Here is an alternate approach. Here we assume that the work function is overcome by the incoming light energy Note that the work function was not stated, so we must assume that it is overcome by the incoming light energy The light wavelength angstroms should be represented in "m" , as Planck's constant has "m". Therefore, the energy contained in one photon of that wavelength is:. Now, the intensity of light can be treated as if it were an energy value for all the photons involved, since we retain all the units beyond "J".

The Sun emits light in all colors, but since yellow is the brightest wavelength from the sun, that is the color we see with our naked eye. Specialized instruments can observe light far beyond the ranges visible to the naked eye. Updated multiple times daily. This channel as well as AIA is designed to study solar flares. It measures extremely hot temperatures around 6 million Kelvin It can take images every 2 seconds instead of 10 in a reduced field of view in order to look at flares in more detail. It measures extremely hot temperatures around 10 million K 18 million F , as well as cool plasmas around , K , F.
