<em><u>Answer:</u></em>
The circuit is said to be <u>closed</u>
<em><u>Explanation:</u></em>
Electricity is defined as the movement of electrons within a conductor in a certain path.
<u>This means that, for electricity to flow, two conditions need to be fulfilled:</u>
1- there must be conductor materials for electrons to move through
2- a closed path (loop) must exist to allow the flow of electrons
If wither of these conditions is not met, the movement of electrons will be stopped and therefore, electricity will not be conducted
<u>Based on the above,</u> when all parts of a circuit are composed of conducting materials (conductors forming closed path), the circuit is said to be closed (a loop exists for electrons to move in).
Hope this helps :)
When the incident light is yellow the width of the central band greater. Single-wavelength light sources are known as monochromatic lights, where mono stands for one and chroma for color. Monochromatic lights are defined as visible light that falls inside a specific range of wavelengths. It has a wavelength that falls within a constrained wavelength range.
A laser beam is the ideal illustration of monochromatic light. A monochromatic light beam produced by a single atomic transition with a particular single wavelength is what makes up a laser. A color scheme that consists solely of different shades of one color is referred to as monochromatic.
