Write a note on wave-particle duality, which became evident in the early part of the 20th century. state the simple equations that relate the wave and particle properties of matter and light and explain their meaning. give an example and a brief description of two experiments: one that shows the wave nature of matter, and another that shows the particle nature of electromagnetic radiation.

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

Which object is most likely represented by a dot?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
