Diverging Lenses _ GCSE Physics

The video tutorial explains the differences between converging and diverging lenses. Diverging lenses refract light to create virtual images that cannot be projected onto a screen. These images are upright and diminished. The tutorial also covers how to draw ray diagrams for lenses, showing the path of light rays through the lens. Finally, it mentions the application of diverging lenses in correcting short-sightedness.

What is the primary function of a diverging lens?

• To spread light outwards

• To focus light into a single point

• To magnify objects

• To create a real image

Which of the following is true about the images formed by diverging lenses?

• They are real and inverted

• They are virtual and upright

• They are virtual and magnified

• They are real and upright

In a ray diagram for a diverging lens, what happens to a ray that passes through the center of the lens?

• It converges at the principal focus

• It bends towards the principal axis

• It passes straight through without bending

• It reflects back to the object

What is the purpose of drawing ray diagrams for lenses?

• To calculate the weight of the lens

• To determine the material of the lens

• To measure the size of the lens

• To show how light rays interact with the lens

Diverging lenses are commonly used to correct which vision problem?

• Short-sightedness

• Color blindness

• Long-sightedness

• Astigmatism
