Understanding Light and Atomic Theory

What was the model of the atom discussed in Chapter 3?

• Bohr Model

• Planetary Model

• Quantum Model

• Electron Cloud Model

Which two variables are essential to understanding a beam of light?

• Amplitude and Speed

• Phase and Direction

• Wavelength and Frequency

• Intensity and Color

What is the relationship between wavelength and frequency?

• Inverse relationship

• Direct relationship

• No relationship

• Exponential relationship

What is the speed of light in meters per second?

• 3.00 x 10^6 m/s

• 1.86 x 10^5 m/s

• 3.00 x 10^8 m/s

• 2.99 x 10^8 m/s

If the wavelength of light is known, how can you find its frequency?

• Subtract the speed of light from the wavelength

• Add the speed of light to the wavelength

• Divide the speed of light by the wavelength

• Multiply by the speed of light

What unit is used for frequency in the SI system?

• Meters

• Seconds

• Hertz

• Cycles

How do you convert nanometers to meters?

• Multiply by 10^6

• Divide by 10^6

• Divide by 10^9

What happens to frequency as wavelength decreases?

• Frequency decreases

• Frequency increases

• Frequency becomes zero

• Frequency remains constant

What is the formula to calculate the speed of light using wavelength and frequency?

• Speed = Wavelength + Frequency

• Speed = Frequency / Wavelength

• Speed = Wavelength * Frequency

• Speed = Wavelength / Frequency
