what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
when white light strikes a prism, what happens and why?
when
white light strike a medium, it
disperse,because thewhite light has spectrum with different
wavelength, and wavelength changes when a light move from one medium to
another.
