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
