Quantum physics is a branch of science that studies how matter and energy behave at the smallest scales like atoms and subatomic particles. Unlike classical physics, which explains everyday objects like cars and planets, quantum physics deals with strange and often unintuitive behaviors. For example, particles can exist in more than one state at a

Leaves change color in autumn due to changes in daylight and temperature, which signal trees to prepare for winter. During the growing season, leaves are green because of chlorophyll, the pigment that helps plants absorb sunlight for photosynthesis. As days grow shorter and cooler, chlorophyll production slows down and eventually stops. When the gr

Solar panels work by converting sunlight into electricity using a technology called the photovoltaic (PV) effect. Each panel is made up of many solar cells, usually made from silicon, which absorb photons from sunlight. When these photons hit the silicon atoms, they knock electrons loose. These free electrons are then directed by an electric field

A rainbow is a beautiful natural phenomenon that occurs when sunlight interacts with raindrops in the atmosphere. The process behind a rainbow involves three main actions  reflection, refraction, and dispersion. As sunlight enters a raindrop, it bends (refracts) and then reflects off the inside surface of the drop. When it exits the droplet, the l
