Concept explainers

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

consider an object 2 cm tall and the object located 6 m to the left of ( -2D) spectacle lens, Calculate the position and height of the image for in case of convergence and divergence lens?

Expert Solution

Step 1

The negative power of a lens represents that the lens is a diverging lens. Since two different cases are provided in the question so the same power is used by changing the sign for the converging lens to solve this problem.

For the converging lens:

The thin lens formula is:

Substitute the known values and solve.

Step 2

Magnification of the converging lens is:

Substitute the known values and solve for image height.

Step by step

Solved in 4 steps with 8 images
