Name any 2 elements that are used in fabricating solar cells?
Silicon and germanium
A laser beam is incident on wet piece of filter paper atop a sheet of glass whos index of refraction is to be measured what is the index of refraction of the glass?
n = [(R/2)2 + t2]1/2/R/2t is the thickness of the glass plate, R is the inner radius of the outer bright ring you see
What is the difference from reflection and refraction?
REFLECTION: 1It is the phenomena in which a ray of light after striking a surface retuns back to the same medium. 2.reflection is carried out by the help of mirrors such as concave and convex mirrors. REFRACTION: 1.when a ray of light travels from one medium to another medium its speed changes and this change in speed causes refraction of light. 2.it is caused by lenses such as concace and convex lenses.
What is the index of refraction of transparent materials?
Greater than 1.0Generally, values can be any number greater than 1.0 (which is the refractive index of a vacuum). They are generally listed as real numbers, but in fact can have an imaginary component. They can in fact also be negative, but that's only for very special materials, and not at all common. Any normal material will not have an index of refraction less than 1.
What speed does light travel through transparent objects?
It varies, depending on the material. Typical speeds are about 2/3 the speed of light in a vacuum. Search for a table of "index of refraction" for different materials. If a certain material has an index of refraction of 1.5, that means the speed of light in that material is 1.5 times slower than in a vacuum, so you calculate 300,000 km/sec divided by 1.5 = 200,000 km/sec (where the first speed is the speed of light in a vacuum, and the second is the speed of light in the particular material).
Why silicon is preferred over other materials in designing ic?
because1) knee voltage of silicon is .7V where as germanium has .3V 2)silicon breakdown take place at around 200 0C and germanium at 90 0C
What is the chemical formula for germanium sulfite?
The chemical formula for germanium sulfite is Ge(SO3)2
What is the energy level for germanium?
The energy level for germanium is 4. You know its 4 because of the period its in for example: beryllium is in row 2 period 2 so the energy level is 2.
How many inner shell electrons does germanium have?
2
What do you call a germanium if you remove 2 protons?
a zink isotope
What is the history of germanium diode?
Germanium point contact diodes were first created and used during World War 2 as detectors in microwave RADAR systems, as the vacuum tubes available at that time did not operate at microwave frequencies. Shortly after World War 2 germanium junction diodes were created.
What is the difference between refraction and transmission?
the difference is transmission occur in same medium,but refraction occurs whn 2 medias are there,its actually bending of light at interface of 2 medias
What do you call a germanium atom if you remove 2 protons?
a zink isotope
What 2 molecules contain germanium?
Many simple organic compounds can have germanium substituted for some or all of the carbon. This gives many thousands of different molecules.

What is the index of refraction of a material if the angle of incidence in air is 50 degrees and the angle of refraction in the material is 40 degrees?
When a ray of light passes from material 1 to material 2: N1 sin θ1 = N2 sin θ2 where N1 & N2 are the refractive indices of the materials, and θ1 is the angle of incidence, θ2 the angle of refraction. From air to the material: N1 = 1.00, θ1 = 40°, θ2 = 50°, N2 = unknown, the index of refraction of the material: → 1.00 x sin 50° = N2 x sin 40° → N2 = 1.00 x sin 50° ÷ sin 40° → N2 ≈ 1.1917 (the index of refraction of the material)
What does iron and germanium have in common?
Iron and germanium are both chemical elements on the periodic table. They are both metals and have similar properties such as being solid at room temperature, having high melting and boiling points, and being good conductors of electricity. However, iron is a transition metal and germanium is a metalloid.
