Convex Lens Focal Length Quiz

What is the primary aim of the experiment involving a thin convex lens?

• To measure the thickness of the lens

• To observe the color dispersion through the lens

• To determine the focal length by capturing an image of a distant object

• To calculate the refractive index of the lens

Which of the following is NOT listed as a required material for the experiment?

• Light source

• Lens holder

• Semi-transparent screen

• Thin convex lens

What should you do to obtain a sharp and clear image of the distant object?

• Rotate the lens

• Tilt the screen

• Move the screen back and forth

• Move the lens back and forth

How is the focal length of the lens determined in this experiment?

• By measuring the diameter of the lens

• By calculating the distance between the lens and the object

• By measuring the distance between the screen and the optical center of the lens

• By observing the color of the image

What is the final step in the experiment to determine the focal length?

• Repeat the experiment once

• Adjust the lens position

• Calculate the mean value of the focal lengths

• Record the first observation
