Physical optics (Give the definition of diffraction. Write the condition of destructive interference observation. What is diffraction grating?)

Physical optics

1.Give the definition of diffraction.

2. What is wave front? Draw circular and plane wave front.

3. What is interference of light?

4. When two waves can interfere?

5. Write the condition of constructive interference observation.

6. Write the condition of destructive interference observation.

7. What is diffraction grating?

8^*. Light from a laser with wavelength l is directed towards diffraction grating. The distance between the 0-diffraction maximum and 1-diffraction maximum is equal a, the distance from the diffraction grating is b. Calculate using formula for diffraction grating the period of diffraction grating d.
