Which two ways can light be understood

1 answer:

3 0

Around 1700, when Mechanics was made for the first time by Sir Isaac Newton, he said about the nature of the light that it resembles thiny particles. Somewhat latter , around 1865, Maxwell discovered that the Electromagnetic waves have the same speed as the speed of light. From this resemblance he deduced that light should be an Electromagnetic wave. Latter than this, at around 1900, when trying to explain some peculiarities of the Photoelectric effect, Eistein postulated that light behaves like thiny particles (the older Newton Theory from 1700).
Today we say that LIGHT HAS A DUAL CHARACTER. It is also a wave and a particle. In some experiments light behaves like an Electromagnetic wave (diffraction, reflection, refraction), in other experiments light behaves like thiny particles (quanta): the Photoelectric effect and the Compton effect.

Name some devices we use to make measurements

Answer:

Explanation:

Ruler. A steel ruler aids the measurement and layout of straight lines. The ruler, also called "straightedge" or "straight-edged ruler," is a long, thin strip of wood, metal or plastic marked with increments of measurement.

Measuring Tape. The modern measuring tape's roughly palm-sized casing contains a coiled strip of metal marked with increments of measurement. The metal strip, called "tape," attaches to a spring which automatically retracts the tape into the casing following use.

Walking Tape Measure. The walking tape measure, also called "surveyor's measure," records the distance traveled by a wheel. An operator pushes the measure's wheel, similar to a bicycle wheel, by a handle as an attached ticker box displays feet or meters in the same format as a car's odometer.

Laser Measure. The laser measure offers point and shoot distance measurement. In its most basic form, a laser measure is a hand-held electronic device with a digital display.

Below are the examples of work being done on an object

Carrying a box up a flight of stairs.

Lifting a bag of groceries.

Lifting a rock off the ground.

Pushing a grocery cart through the store.

<h3>Workdone</h3>

Work is said to be done when a force applied moves a distance

Work done = force × distance
