In this lab, you can explore refraction with a lens. You can modify the focal length, height, and position of the object and observe the image formed through refraction.
You can choose between a 'converging' and 'diverging' lens.
How does the height of the image change?

Online labs provide your students with the possibility to conduct scientific experiments in an online environment. Remotely-operated labs (remote labs) offer an opportunity to experiment with real equipment from remote locations. Virtual labs simulate the scientific equipment. Data sets present data from already performed lab experiments. Please use the filters on the right to find appropriate online labs for your class. Labs can be combined with dedicated Apps to create Inquiry Learning Spaces (ILSs).
If you are looking for online labs especially suitable for the curricula of Benin, Kenya or Nigeria, please visit our Collections page.

This lab shows a marching band model for refraction. We're looking at an overhead view of five rows of the marching band. When the band moves from one surface (say, a parking lot) to a different surface (say, a grassy field), the speed of the marchers can change.
Let's say you have two points, and you want the light to travel from one point to the other. In this simulation, by the way, the first point is colored red and the other point is colored purple.
This lab builds of the lab titled, 'Refraction and the role of time'.
The light source can either be the red dot in medium 1 or the purple dot in medium 2. In either case, the light is incident on the interface between the two media at the position of the green dot, which is fixed.
In this lab, you can explore the refraction of light through a rectangular block (you can modify its refraction index). The light is emitted by the red dot, which is in air. The light strikes the side of a rectangular block.
In this lab, you can explore refraction through 3 media. The light is emitted by the red dot, which is in the air. The light enters medium 2, and then continues on to medium 3. Before adjusting either slider, make two predictions.
In this lab, you can explore the phenomenon of total internal reflection (such as an in a optic fibre). The light source is the purple dot in medium 2. The light is incident on the interface between the two media at the position of the green dot, which is fixed.
This lab demonstrates how a prism works. White light shines in from the left. You may be surprised to see that it goes straight into the prism, without splitting up inside the prism. Why is this? This is something of a special case.
