Imagine you are a stationary observer and see a spaceship moving from left to right. A person sitting in the spaceship turns a flashlight on and you can \"observe\" the light travel to the top of the spaceship and back down. To the observer on the spaceship, the light appears to move straight up and straight down, but to you, the light travels at a diagonal as shown in the image below. velocity 1 2 5 3 Seen by observer Seen by observer not moving with moving with respect to the spaceship spaceship A B We know that light travels at the speed of light, c, regardless of the movement ofthe source and observer. The velocity of the light, c, would equal the distance covered divided by the time it takes to cover that distance in both cases. We'll call the time in A to and the time in B, t. Question 1 From the observer within the spaceship, what is din terms ofthe speed of light? Question 2 If the velocity of the spaceship is v, what distance, 0, does the spaceship cover horizontally during the time for the light to reach the ceiling? Question 3 In B, what distance, L, does the light cover in that same time? Question 4 Label the diagram below with the values in questions 13 where they belong. Question 5 Using Pythagorean Theorem, substitute the appropriate values into the equation and solve for tin terms of to? The energy levels for a Bohr atom are shown below. -0.54 ev n = 5 -0.85 eV n = 4 -1.51 eV n = 3 -3.40 ev n = 2 -13.6 ev n= 1 What amount of energy is needed for an electron to jump from n = 1 to n = 3? (h = 6.626 x 10-34, 1 eV = 1.6 x 10-19 J) 12.8 eV 10.2 ev 13.1 eV 12.1 eV.Aftel two halflives, how much of the original sample would remain? Q 6.25% Which of the following relativistic statements seems to contradict what we know in classical physics? O The laws of physics are the same in all frames of reference that are moving uniformly. O Waves had to have some medium to travel through. O The speed of light is constant and is independent of the motion of the source or the observer. A beam of light that travels parallel to the aether would take longer than the beam that travels perpendicularly to the aether.. lWhat are control rods in a nuclear reactor? 3 they are used for emergency notification they control the intensity of the chain reaction 3 they absorb energy from the reaction to transmit 3 they serve to fuel the nuclear reaction . Which ofthe following are true regarding beta minus decay? (Select all that apply) :I emits a neutrino emits an antineutrino the nucleus emits a highenergy electron :I the nucleus emits a highenergyr positron Who was the first scientist to include electrons in the atomic model? Thomson Dalton Bohr RutherfordThe energy levels for a Bohr atom are shown below. -0.54 ev n = 5 -0.85 ev n = 4 -1.51 ev n = 3 -3.40 ev n = 2 -13.6 eV n = 1 If an electron moves from n = 5 to n = 1, what wavelength of light is emitted?

Bohr Shrodinger Rutherford ThomsonWhich of the following best describes a frame of reference? a point in which someone relates the behavior of an object from one perspective the theory that describes the behavior and characteristics of objects moving at relativistic speeds D the effect of the slowing of time as an object moves with high speeds an experiment that proved that Earth did not have an aether wind. Which of the following can be used to describe nuclear fission? Check all that apply. used in atomic bombs used in nuclear reactors energy is released as light not very efficientA photon has 1.86 ev of energy. What is the photon's wavelength? (h = 6.626 x 10-34, 1 eV = 1.6 x 10-19 J) 428 nm 345 nm 218 nm O 665 nm. According to the Michelson and Morley experiments. which of the following is NOT true? 3 The laws of physics are the same in all frames of reference that are moving uniformly. D Waves had to have some medium to travel through. A beam of light that travels parallel to the aether would take longer than the beam that travels perpendicularly to the aether. 3 The speed of light is constant and is independent of the motion of the source or the observer.
