at this test of spmb still about Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light)
The study of light and the interaction of light and matter is termed optics. then optic The observation and study of optical phenomena such as rainbows and the Aurora Borealis offer many clues as to the nature of light as well as much enjoyment.
other test about mechanism , A mechanism is some technical aspect of a larger process or mechanical device, a part or combination of parts designed to perform a particular function,The scientific definition of a machine is any device that transmits or modifies energy. In common usage, the meaning is restricted to devices having rigid moving parts that perform or assist in performing some work and then about kinetics Kinematics (Greek ??????, to move) is a branch of mechanics which describes the motion of objects without the consideration of the masses or forces that bring about the motion. By contrast, dynamics is concerned with the forces and interactions that produce or affect the motion
then dynamical test,dynamics is the branch of classical mechanics that is concerned with the effects of forces on the motion of objects. The former distinguishes it from kinematics and the latter distinguishes it from statics. In quantum physics, dynamics may refer to how forces are quantized, as in quantum electrodynamics or quantum thermodynamics’s.
