Electromagnetic waves

I can recognise, draw and describe how light and other waves can reflect from different surfaces, using rays and wavefronts.

I can describe what refraction is and draw accurate ray diagrams of refraction.

I can describe what refraction is, draw accurate diagrams of refraction and use the idea of wavefronts to explain what causes refraction.

I can describe and explain when refraction happens and when total internal reflection happens at boundaries between media.

I can use a convex lens to form an image on a screen, and describe how the image can vary depending on the object distance.

I can use a converging lens to form an image on a screen, and describe how the image can vary depending on the object distance.

I can describe uses of converging lenses and draw scale ray diagrams to determine the position of an image.

I can describe uses of convex lenses and draw scale ray diagrams to determine the position of an image.

I can describe the formation of virtual images by convex and concave lenses and draw ray diagrams to find the position and magnification of the image.
