An optical technician is working in a darkened laboratory. They want to project a sharp, clear image of a highly illuminated calibration target, which is located at the far end of the room, onto a mobile projection screen using a single converging lens.
Describe the procedure the technician should follow to successfully project this sharp image onto the screen.
24 exam-style questions on Edexcel GCSE Physics 5.1 Reflection, refraction and lenses, covering 5.1.1 Reflection, refraction and total internal reflection, 5.1.2 Specular and diffuse reflection, 5.1.3 Colour of light: absorption and filters, 5.1.4 Lenses: power, focal length and shape, 5.1.5 Ray diagrams for converging and diverging lenses, and 5.1.6 Real and virtual images. Each one has a worked solution and a mark scheme showing where the marks go.
