What happens when waves interact with matter? | The can be reflected, transmitted or a combination of both. |
Can waves that are transmitted be refracted? | No |
Waves that strike a surface that is transparent, like water, at an angle, there direction changes are called what? | Refracted |
What happens when waves fall on a transparent medium? | Waves are partly reflected and partly refracted |
What is reflection? | Reflection is the bouncing back of particles or wave that strikes a boundary between two media. |
What is the law of reflection? | The law of reflection states that the angle of incidence and the angle of reflection are equal to each other. |
What is an incident wave? | A light wave that strikes a boundary. |
What is a reflective wave? | A light wave that bounces off a boundary. |
What is a normal? | A normal is a line drawn perpendicular to the point where the incident ray strikes the barrier. |
What kind of images do plain mirror produce? | Virtual images |
What are the shapes that plain mirrors can be grouped by? | Plane, convex, and concave |
What is an image? | An image is a likeness or reproduction of an object. |
What is the difference between virtual and real? | Virtual images in a mirror are images that seem to be in or behind the mirror and are always upright. Real images are formed by converging light rays and can be displayed on a screen. These images are inverted. |
What is an echo? | An echo is a reflective sound. |
What happens when light is incident on a rough surface? | It is reflected in many directions. |
