      • Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray.

  1. 1. reflects and absorbs light so NO light goes through 2. cannot see objects through them what is the ray model of light 1.light follows a predictable path of light. this model is also used to describe how light interacts with mirrors

  2. Study with Quizlet and memorize flashcards containing terms like What is a light ray?, What happens when light rays strike objects?, What is the difference between transparent, translucent, and opaque? and more.

  3. Light slows when it passes through matter, light changes direction, and light scatters. Study with Quizlet and memorize flashcards containing terms like How can matter interact with light?, How does matter transmit light?, Transparent and more.

  4. If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The diagram below illustrates the law of reflection.

    Atoms and molecules contain electrons. It is often useful to think of these electrons as being attached to the atoms by springs. The electrons and their attached springs have a tendency to vibrate at specific frequencies. Similar to a tuning fork or even a musical instrument, the electrons of atoms have a natural frequency at which they tend to vib...

    Reflection and transmission of light waves occur because the frequencies of the light waves do not match the natural frequencies of vibration of the objects. When light waves of these frequencies strike an object, the electrons in the atoms of the object begin vibrating. But instead of vibrating in resonance at a large amplitude, the electrons vibr...

    The color of the objects that we see is largely due to the way those objects interact with light and ultimately reflect or transmit it to our eyes. The color of an object is not actually within the object itself. Rather, the color is in the light that shines upon it and is ultimately reflected or transmitted to our eyes. We know that the visible li...

  5. In the situations shown here, light interacts with objects large enough that it travels in straight lines, like a ray. Experiments, as well as our own experiences, show that when light interacts with objects several times as large as its wavelength, it travels in straight lines and acts like a ray.

  7. The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction principles are combined with ray diagrams to explain why lenses produce images of objects.
