What happens to the width of the central diffraction pattern (in the single slit experiment) as the slit width is changed and wh
Leno4ka [110]

Answer:

width of fringes are increased

Explanation:

The width of central maxima is given by the following expression

Width = 2 x Dλ / d

  1. D is distance of screen from source , d is slit width and λ is wavelength of light source.
  2. Here we see , on d getting decreased , width will increase because d is in denominator .

Due to increased width ,  position of a fringe  moves away from the centre.

What are the main forms of energy? Define each type
Fed [463]
Thermal energy - the internal kinetic energy in a substance caused by vibration of atoms and molecules. Thermal energy is also known as heat.

Radiant energy - is the electromagnetic energy that travels in waves. Radiant energy is kinetic energy that includes light, x-rays, microwaves, and radio waves.

Elastic energy - potential energy produced from stored or released elastic materials. This is stored mechanical energy energy resulting from being stretched or compressed.

Mechanical energy - the energy an object possesses due to movement. Mechanical energy is kinetic energy because it is the movement from one position to another.

Gravitational energy - the potential energy an object has because of position. This is produced from gravitational force acting upon an object.

Chemical energy - the potential energy stored in the bonds of molecules and compounds.

Nuclear energy - potential energy stored in the core (nucleus) of an atom.

Electrical energy - the kinetic energy produced from the movement of an electric charge.
