Physical Science Semester Exam Review-Waves

What is the formula for wave speed?

• Wave speed = frequency + wavelength.

• Wave speed = frequency × wavelength.

• Wave speed = frequency / wavelength.

• Wave speed = wavelength - frequency.

What is the law of reflection?

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence is greater than the angle of reflection.

• The angle of incidence is less than the angle of reflection.

• The angle of incidence is perpendicular to the angle of reflection.

What is the electromagnetic spectrum?

• The electromagnetic spectrum is the range of all types of electromagnetic radiation.

• The electromagnetic spectrum is a type of sound wave.

• The electromagnetic spectrum refers to the visible light only.

• The electromagnetic spectrum is a measure of gravitational waves.

What type of wave is sound?

• A. Electromagnetic wave

• B. Mechanical wave

• C. Transverse wave

• D. Longitudinal wave

What is a wave's amplitude?

• The speed of the wave's propagation.

• The maximum displacement of points on a wave from its rest position.

• The frequency of the wave's oscillation.

• The wavelength of the wave.

What is the relationship between wavelength and frequency in the electromagnetic spectrum?

• As the wavelength decreases, the frequency increases.

• As the wavelength increases, the frequency increases.

• Wavelength and frequency are unrelated.

• Wavelength is inversely proportional to frequency.

What is refraction?

• The reflection of light off a surface.

• The bending of a wave as it passes from one medium to another.

• The absorption of light by a medium.

• The scattering of light in different directions.

What is interference in wave behavior?

• Interference is the phenomenon that occurs when two waves meet and combine to form a new wave.

• Interference is the process of waves bouncing off surfaces.

• Interference is the change in direction of waves when they pass through a narrow opening.

• Interference is the increase in amplitude of a wave when it travels through a medium.

What happens to the amplitude of a sound wave when its energy increases?

• The amplitude decreases, causing the sound to get quieter.

• The amplitude remains the same, and the sound stays at the same volume.

• The amplitude increases, causing the sound to get louder.

• The amplitude fluctuates randomly, affecting the sound quality.

What is a medium in the context of wave propagation?

• A medium is the substance through which a wave travels.

• A medium is a type of wave that travels through a vacuum.

• A medium is a device used to measure wave frequency.

• A medium is the energy carried by a wave.
