PHYS 165 MODULE 1 TEST BANK FULL
SOLUTION VERIFIED QUESTIONS AND
ANSWERS GUARANTEED TO PASS
●● Which of the following is a continuous variable ?
A) Number of students in a class
B) Time spent exercising per week
C) Number of M&Ms consumed
D) You Answered Age (in years)
Answer: B) Time spent exercising per week
- speed of a car
●● Which of the following is a quantized variable?
A) Velocity of a falling object
B) Position of a Truck
C) Speed of a sound wave
D) Energy of a Purple Photon
Answer: Energy of a purple photon
The number of people attending a concert is a quantized variable. There
is a smallest value - one person, and all possible values are integer
multiples of that smallest value.
, ●● The discovery of the electron is credited to which experiment?
A) The Rutherford Gold Foil Experiment
B) J. J. Thompson's Cathode Ray Tube Experiment
C) The Compton Scattering Experiment
D) The Millikan Oil Drop Experiment
Answer: B) JJ Thompson's Cathode Ray Tube Experiment
●● True or False: Max Planck proposed that a blackbody is made up of
tiny oscillators.
Answer: True
- He proposed that a blackbody is made up of tiny oscillators (atoms or
groups of atoms) and that these oscillators can only give off energy
when their own energy changes by certain amounts.
- Frequency of their vibration depends on the temperature of black body.
More the temperature of black body, more the frequency of oscillation of
tiny oscillators.
- Energy from the oscillator is quantized
●● What was Planck's revolutionary assumption about a blackbody that
enabled him to explain the experimental observations of the radiation
from a blackbody?
