When light hits an object, three things can happen:
π Reflection β Light bounces off (like a mirror).π§ Refraction β Light bends when it passes through something (like water or glass).β« Absorption β Some materials soak up light and become warm.Thatβs why a black shirt feels hotter than a white one in the sun βοΈπ€.

π X-rays β used by doctors to look inside the body.
All these are forms of light energy traveling in waves! πβ‘
