In a laboratory experiment, a microwave generator is used to produce a beam of monochromatic microwaves. These waves are incident on a series of metal tubes that forms a diffraction grating. The metal tubes are spaced 2.20 cm apart. When the microwave signal passes through the grating, a receiver placed 25.0 cm from the grating detects a maximum signal. A first-order maximum signal is also detected at each of positions I and II, as labelled in the diagram below. The angle from the central maximum to either Position I or II is 25.00 Grating Position I Receiver Microwave generator Position II Note: This diagram is not drawn to scale. The experimental wavelength of the microwaves, in centimetres, is a.bc cm. Record a, b and c in the space provided. Answer:Use the following information to answer the next question. In certain situations, electrons demonstrate particle-like characteristics, and in other situations, they demonstrate wave-like characteristics.
