A straight beam of light is called a ray of light. Rays of light travel in a straight line from their source until they are interrupted or reflected by a surface.
Light travels in a straight line, moving in a straight path known as a ray.
Light ray and gamma ray both travel in a straight line.
A straight line that represents a light wave is called a ray. It is a simplified representation of the path along which light travels. Rays help us understand how light interacts with objects and surfaces.
A straight line that represents a light wave is called a ray. It is used to show the direction of light propagation in geometrical optics.
A ray emitted from a light source is called a light ray. It represents the path that light travels in a straight line from the source in a specific direction.
You can use a pencil, pen, or chalk to draw a light ray on paper or any other surface. Make sure to use a straight edge, like a ruler, to keep your light ray in a straight line.
