Aconverging lens (f1 = 12.1 cm) is located 32.4 cm to the left of a diverging lens (f2 = -5.4 cm). a postage stamp is placed 34.5 cm to the left of the converging lens. locate the final image of the stamp relative to the diverging lens.

The final image of the stamp relative to the diverging lens is 7.01 cm to the left side of the diverging lens.

Explanation:

Given that,

Focal length of converging lens = 12.1 cm

Focal length of diverging lens = -5.4 cm

Object distance = 34.5 cm

We need to calculate the image distance for converging lens

Using lens formula

Put the value into the formula

We need to calculate the image distance for diverging lens

Object distance is

Using lens formula

Put the value into the formula

Hence, The final image of the stamp relative to the diverging lens is 7.01 cm to the left side of the diverging lens.

the part of the wave he is travelling on is the crest

i don't understand. explain it clearly
