 What is the relationship between a wave’s frequency and energy?

• As the frequency increases, the energy also increases
• As the frequency decreases, the energy increases
• As the frequency increases, the energy decreases
• As the frequency increases, the energy doubles

The pitch depends on the characteristics of the vocal cords.  Women sound more high-pitched than men because their vocal cords are…

• less dense
• longer
• denser
• shorter.

ow are wavelength and frequency related?

• Directly proportional.  When wavelength increases, frequency increases.
• Inversely proportional.  When wavelength increases, frequency decreases.
• Equal
• Constant

Blue light, which is bent more and found in the inner part of the rainbow has…

• lower frequency
• shorter wavelength
• faster speed
• longer wavelength

The formula for distance is…

• Speed / Distance
• Time x Distance
• Speed x Time
• Speed / Time

It could be described in terms of the positions of the moving object at different points in time. It is also defined as the change in position over an interval of time

• Speed
• Motion
• Physics
• Velocity

If the same amounts of negative and positive charge are found in an object it is called…

• Positively Charged
• Negatively Charged
• Neutral Charge
• Net Charge

It is a mode of heat transfer that takes place in fluid and moves in an up and down motion.

• Conduction
• Convection
• Radiation
• Induction

Waves like water waves can move objects like a massive ship travelling from one place to another. What can we infer about waves from the given illustration below?
