Light energy is defined as how nature moves energy at an extremely rapid rate, and it makes up about 99% of the body's atoms and cells, and signal all body parts to carry out their respective tasks. An example of light energy is the movement of a radio signal.
Answer:
to be seen correctly and throughly
Answer:
B) the law of reflection
Explanation:
When a light ray reflects off a surface, it obeys the law of reflection.
A few definitions before giving the law of reflection:
- The angle of incidence is defined as the angle between the incident ray and the normal to the surface
- The angle of reflection is defined as the angle between the reflected ray and the normal to the surface
The law of reflection states that:
- The angle of incidence is equal to the angle of reflection
- The incident ray and the reflected ray lie both on the same plane.
Answer:
A. accelerating
Explanation:
Acceleration is defined as the ratio between the change in velocity and the time taken for the velocity to change:
We must note that the velocity is a vector - so it has both a magnitude (the speed) and a direction.
This means that a non-zero acceleration occurs when:
- the speed changes, or
- the direction changes, or
- both the speed and the direction change
For an object moving at constant speed in a circle, the direction changes, so the object is accelerating.
Answer:
Every object has a different density and therefore carries different properties. When rays of white light strike an object, each ray light strikes the object with different frequency and therefore is absorbed and reflected differently from the host object.
In case if all the frequencies are absorbed by the object, it turns out to be black in color. Whereas on the other hand, if it is a mix of absorption and reflection, it makes different colors based on its frequencies and other properties of the object.
