hoa [83]

The actual length of the dust termite observed under the microscope is 1.5 mm

  • The scale of image produced under the microscope 100 : 1

  • This means image is magnified 100 times its original size as microscopes are used to enlarge or magnify the size objects.

  • Taking the measured size of the dust termite under the microscope in millimeter = 150 mm

The actual length of the termite will be :

  • Measured size under microscope ÷ 100

  • 150 mm ÷ 100

  • 1.5 mm

Therefore, the actual length of the dust termite is about 1.5 mm
