题目 Light and ReflectionLight is another type of wave that carries energy. A source of light (光源) such as the sun or a light bulb gives off light rays that travel away from the light source in all directions.A light ray is a narrow beam (光束) of light that travels in a straight...
When a light ray hits a surface (表面) and is reflected, the reflected ray obeys the law of reflection. The angle of incidence (入射角) is always the same as the angle of reflection. This is the law of reflection. And this is true for any surface, no matter what material it is ma...

What type of wave is light wave? Light as a wave: Light can be described (modeled) as anelectromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ...
Practice An EM wave is traveling through outer space with a frequency of 8.0 x 1013 hertz. What is the wavelength of this wave? v = fλ λ= v / f λ = (3.0 x 108 m/s) / (8.0 x 1013 Hz) λ = (3.8 x 10-6 m) What type of wave is this? Infrared ...
