A tuning fork oscillates with a frequency of 256 hertz after being struck by a rubber hammer. Which phrase best describes the sound waves produced by this oscillating tuning fork?

mechanical waves that require a medium for transmission

electromagnetic waves that require no medium for transmission

electromagnetic waves that require a medium for transmission

mechanical waves that require no medium for transmission

Waves pass through a 10 centimeter opening in a barrier without being diffracted. This observation provides evidence that the wavelength of the waves is

longer than 10 cm, but short than 20 cm

As a sound wave passes from water, where the speed is 1.49 x $$10^3$$ m/s, into air, the wave's speed

decreases and its frequency remains the same

increases and its frequency remains the same

remains the same and its frequency decreases

remains the same and its frequency increases

A wave is diffracted as it passes through an opening in a barrier. the amount of diffraction that the wave undergoes depends on both the

wavelength of the incident wave and the size of the opening

amplitude and frequency of the incident wave

wavelength and speed of the incident wave

amplitude of the incident wave and the size of the opening

A source of waves and an observer are moving relative to each other. the observer will detect a steadily increasing frequency if

he accelerates toward the source

he moves toward the source at a constant speed

the source moves away from him at a constant speed

the source accelerates away from him

Which pair of terms best describes light waves traveling from the Sun to Earth?

electromagnetic and longitudinal

A microwave and an x ray are traveling in a vacuum. Compared to the wavelength and period of the microwave, the x ray has a wavelength that is

shorter and a period that is shorter

longer and a period that is shorter

longer and a period that is longer

shorter and a period that longer
