The power output of a laser is measured by its wattage, that is, the number of joules of energy it radiates per second (1 W= 1 J s-1). A 10-W laser produces a beam of green light with a wavelength of 520 nm (5.2 × 10-7m).(a) Calculate the energy carried by each photon.(b) Calculate the number of photons emitted by the laserper second.
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
