(i) Suppose the speed of light was 100km/hr. Explain 3 ways your life would be different.
(ii) A mirror is moving towards you at the speed of v. You shine a torch at the mirror and it reflects back towards you. What is the speed of the light in the reflected beam?
(iii) Is there any change in properties of the reflected light? Please explain.

PHOTOELECTRIC EFFECT LAB Enter your answers to Canvas. Objectives: The main objective of this lab is to observe the photoelectric effect experiment qualitatively. From the observations, you will summarize the important relationship between the properties of the photoelectrons (average speed, kinetic energy) to the properties of the incident light (wavelength, frequency). You will...

06M.3 Suppose we prepare a beam of photons with wave- length λ and intensity I whose spin angular momentum vectors are aligned with their direction of motion, and we allow these photons to fall on a circular metal plate of mass M and radius R that is free to rotate around an axis per- pendicular to the plate and parallel to the beam of light. As the photons are absorbed by the metal plate, the plate will have to rotate...

Wave aspects of matter and of light [Accompanies Sections 26-3 and 26-4] (a) Rank the following particles in order of their de Broglie wavelength, from longest wavelength to shortest wavelength. If any two particles have the same de Broglie wavelength, state this. Explain how you made your ranking. (i) A proton (mass 1.67 x 10-27 kg) moving north at 1.0 x 10 m/s (ii) A proton (mass 1.67 x 10-27 kg) moving west at 2.0 x 10 m/s...

STEP 1: In your own words define problem employees and the categories they may fall into. For the second or last paragraph provide your opinion on which employee type is the most difficult. DEFINITION : I think that "problem employees" are employees that either directly or indirectly hinder the organization's mission or vision, and break down into roughly four categories. In general, problem employees can be classified into two broad categories - employees creating problems for the organization and employees...

The Case Study in Cancer Part I Ann is a 27-year-old nurse working at the local hospital in surgery. She had worked hard to move into the specialty, and she was enjoying her career, friends, and family. She and her partner had been living together for about a year, and she was content. As a nurse, Ann knew the importance of doing breast self-exams, and did them regularly. In the shower one morning, she felt a lump she wasn’t familiar...
