Year 11 Physical

I can explain the properties, uses and dangers of non–ionising electromagnetic radiation.

I can explain the properties, uses and dangers of ionising electromagnetic radiation.

I can describe how to investigate the emission of infrared by different surfaces, state what is meant by a ‘black body’ radiator and explain how radiation affects an object’s temperature.

I can investigate how the intensity of black ink affects the infrared radiation absorbed by a surface.

I can explain what is meant by the spectrum of electromagnetic waves.

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.

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

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 describe what is different about light of different colours and explain the apparent colour of objects when illuminated with different colours of light.

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