What are the rays from the sun to the moon called?
Moonlight. it is the light that comes to Earth from the Moon. This light does not originate from the Moon, but is actually reflected sunlight. In many legends and fantasy games, moonlight is an important part of magical processes (for example, werewolves transform at full moon).
What mirror will diverge light rays?
Light rays will be diverged by a convex mirror.
Can Light Be Produced Without Heat?
Light and heat are the same stuff; electromagnetic energy. The difference is in the wavelength of the energy; heat has longer wavelengths than light. (It's all one broad spectrum from radio to heat to light to x-rays to gamma rays to cosmic rays; all electromagnetic energy.
How does the energy from the sun reach the earth?
Waves of heat and light, called radiation, travel to earth.
When light rays from a distant star pass through a lens they converge at a single point called the?
Focus or the focal point.
What do you call the straight path that light travels?
light travels in straight paths called rays
How do light rays travel light ray?
Light Rays travel in straight paths as transverse waves. It needs no medium to travel along.
What are the different lines in geometry called?
segments, lines, and rays.
What is an angle formed by opposite rays called in geometry?
straight angle
How does light ray travel?
Light rays travel in straight paths as transverse waves. It needs no medium to travel along.
What is a real example of a ray in geometry?
A laser, light from a flashlight, and radio waves are all rays
Parallel rays can be made to meet at one place called?
In Euclidean geometry they cannot. In other geometries they can meet at various points, depending on the configuration of the space. In projective geometry, for example, they meet at the "point at infinity". In physics, though, parallel rays (of light, for example), can be made to meet at the focus of a lens or mirror.
What is called ray of light?
light rays
What are the two rays that form an angle?
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
Bending light rays so that they focus on the retina is called?
The bending of light rays so they focus on the retina is called refraction.
A lens that forms images by refracting light rays together is called what?
A lens that forms images by refracting light rays together is called what?
What is A collection of rays of light called?
It is called a beam.
