Question

Waves and Lenses True False

Waves

1. [ ] Constructive interference occurs when two or more waves overlap and the amplitude of the resultant wave is greater than that of any individualwaves.2. [ ] In Young’s double-slit experiment, the condition for constructive interference is that the path difference of two waves must be either zero or some integer multiple of the wavelength.3. [ ] When a light wave traveling from air is reflected on a diamond surface, the reflected wave undergoes a 180° phase change.

Lenses

1. [ ] Single-slit diffraction pattern is resulted from light from one portion of the slit interfering with light from another portion.2. [ ] According to Rayleigh's criterion, any optical device has are solution limit.4. [ ] A diffraction grating consists of a large number of equally spaced, identical slits
