General Physics: Waves

What are the two main types of waves discussed in this lesson?

• Mechanical and Electromagnetic

• Transverse and Longitudinal

• Sound and Light

• Ocean and Air

Which type of wave does not require a medium to propagate?

• Ocean waves

• Waves on a string

• Light waves

• Sound waves

In a transverse wave, how is the medium displaced relative to the direction of wave propagation?

• Circular

• Diagonal

• Perpendicular

• Parallel

What is the relationship between wave speed, frequency, and wavelength?

• Wave speed is the sum of frequency and wavelength

• Wave speed is the product of frequency and wavelength

• Wave speed is the difference between frequency and wavelength

• Wave speed is the ratio of frequency to wavelength

If a wave on a string has a frequency of 10 Hz and a wavelength of 0.25 m, what is its speed?

• 25 m/s

• 2.5 m/s

• 0.025 m/s

• 250 m/s

What happens to the wave speed if the tension in the string is increased by a factor of four?

• It doubles

• It halves

• It quadruples

• It remains the same

What is the effect of constructive interference on wave amplitude?

• It increases the amplitude

• It cancels the wave

• It decreases the amplitude

• It has no effect on amplitude

What is the result of two waves being 180 degrees out of phase with the same amplitude?

• The waves double in amplitude

• The waves remain unchanged

• The waves triple in amplitude

• The waves cancel each other out

What principle is used to determine the resulting wave when two waves overlap?

• Superposition principle

• Reflection principle

• Refraction principle

• Diffraction principle

In destructive interference, what happens to the amplitude of the resulting wave?

• It becomes smaller than the original waves

• It becomes larger than the original waves

• It remains the same as the original waves

• It becomes zero
