WebBeta particles are essentially electrons emitted from the nucleus of a radioactive atom. They are lighter than alpha particles, and can travel farther in air, up to several yards. … WebTherefore, when light moves through the air and onto glass, reflection or refraction happens. These changes occur owing to changes in speed, wavelength, and direction of light. No glass is perfectly transparent. Otherwise, all the light that hits it would pass through undisturbed. A small amount of light gets reflected.

WebWhat can be helpful to consider here is that your statement "light pass[es] through glass" is not entirely correct. Visible light passes through what we consider to be "normal" glass (it is "transparent" -- we can "see through it") but for this same type of glass, ultra violet light does not make it through this glass so easily.

WebElectricity can pass through some objects better than through others. Conductors are materials through which electrons can travel more freely. Copper, aluminium, steel and other metals are good conductors. So are some liquids like saltwater. Insulators are materials in which electrons cannot move around. They stay in place.
