In this activity, pupils will learn about refraction and reflection, and how they’re different. You only need simple bits of ...

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...

You won’t believe your eyes with this week’s experiment! It is all about light! Light can behave in different ways; it can reflect, refract, or be absorbed. In this experiment, you can teach your kids ...

Students use mirror equations to determine the position and type. Students use mirror equations to determine the position, type, and size of mirror images for curved mirrors mathematically. Optical ...

First proposed over thirty years ago, negative refractive index materials bend light in the opposite direction to ordinary materials. However, they were not demonstrated experimentally until 2000.

In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...

The formation of a rainbow requires the observer to be between the sun and falling rain, with the rain in front and the sun behind. Sunlight passes from behind the observer, refracts as it enters each ...
