What is the difference between transverse and longitudinal waves?

• Transverse waves move perpendicular to the direction of energy transfer, while longitudinal waves move parallel.

• Transverse waves move parallel to the direction of energy transfer, while longitudinal waves move perpendicular.

• Both transverse and longitudinal waves move perpendicular to the direction of energy transfer.

• Both transverse and longitudinal waves move parallel to the direction of energy transfer.

Which of the following is a characteristic of radioactive emissions?

• They have long wavelengths and low energy.

• They have short wavelengths and can ionize atoms.

• They do not interact with atoms.

• They have no effect on cells.

What is the equation for wave speed?

• Wave speed = wavelength + frequency

• Wave speed = wavelength / frequency

• Wave speed = wavelength x frequency
