Indicate true (T) and false (F) statements below regarding light and light microscopy. Your answer would be a four-letter string composed of letters T and F only, e.g. FFFF.
( ) Two light waves of the same amplitude and frequency will completely cancel each other out if not perfectly in phase.
( ) If the refractive index of a medium is 1.1, light travels in a vacuum 1.1 times faster than it does in the medium.
( ) The limit of resolution for conventional light microscopy is approximately 0.4 µm, corresponding to the wavelength of violet light.
( ) A light-emitting particle can be detected with a light microscope even if it is several times smaller than the resolution limit of the microscope.

Total destructive interference (complete canceling) only occurs when the two waves are out of phase by exactly 180 degrees. The formal resolution limit of light microscopy is about 0.2 µm.
