The rate at which the location of an object shifts in any direction. Speed is measured as the ratio of the distance travelled to the time it took to cover that distance. Speed is a scalar quantity since it just has a direction and no magnitude.
<h3>Explain about the speed?</h3>
It speaks of the motion of an object. Speed is calculated as distance travelled divided by time. Speed is measured in m/sec. Speed is a scalar quantity equal to the magnitude of the velocity vector. When a thing's speed is higher, it moves more quickly.
Speed refers to the rate at which a distance varies over time. It has a time-distance dimension. As a result, the SI unit of speed is created by combining the basic units of time and distance. As a result, the SI unit of speed is the meter per second (m/s)
The formula for an object's general speed is [Speed = Distance Time]. M/s is the SI unit of speed.

The correct answer is electromagnetic. Lights travel as an electromagnetic wave. In fact, light is an electromagnetic radiation which has a center of the electromagnetic spectrum. Light is visible to the naked eye, and is responsible for an organism's sense of sight.
