Which of the following statements about microscopes are true?

• Light microscopes have a higher resolution than electron microscopes.

• Llight microscopes have a lower resolution than electron microscopes.

• Light microscopes have a higher magnification than electron microscopes.

• Light microscopes have a lower magnification than electron microscopes.

Answer explanation

Light microscopes have a lower resolution and lower magnification than electron microscopes.

Calculate the real size of a cell if its image size is 200 micrometres and the magnification is 400x.

• 800 micrometres

• 500 micrometres

• 80 micrometres

• 0.5 micrometres

Answer explanation

The real cell is 0.5 micrometres: 200 ÷ 400 = 0.5
