How will the wave patterns on the oscilloscope attached to the speaker change as the volume changes? O As the volume increases, the frequency of the wave will increase. O As the volume decreases, the frequency of the wave will increase. O As the volume increases, the amplitude of the wave will increase. O As the volume decreases, the amplitude of the wave will increase.

D, mm 1 0 00000000 The figure shows two waves traveling in the positive-x direction. The amplitude of the resultant wave is O 1.0 mm. O zero. O 1.8 mm. O 1.4 mm. O 2.0 mm.

Under favorable conditions, the human eye can detect light waves with intensities as low as 2.50 × 10−12 W/m2. A) At this intensity, what is the average power incident on a pupil of diameter 8.20 mm in W B) If this light is produced by an isotropic source 15.5 m away, what is the average power emitted by the source? in W

An interface is formed between a block of aluminium (with an acoustic impedance of 1.8 x 107 kg m2 s') and a block of copper (with an acoustic impedance of 4.6 x 107 kg m-2 s-1). Longitudinal sound waves travelling through the aluminium are normally incident on the boundary, and are partially reflected. a) What is the ratio of the amplitude of the reflected wave to that of the incident wave? Number b) What is the ratio of the amplitude of the transmitted wave to that of the incident wave? Number c) What percentage of the incident power is transmitted? Number d) What percentage of the incident power is reflected? Number % Ouit P Sove Questi

A carbon-dioxide laser emits infrared light with a wavelength of 10.6 μm.     Part A What is the length of a tube that will oscillate in the mmm = 210000 mode?     Part B What is the frequency? Express your answer with the appropriate units.     Part C Imagine a pulse of light bouncing back and forth between the ends of the tube. How many round trips will the pulse make in each second?

Electromagnetic waves can form standing waves. In a standing wave pattern formed from microwaves, the distance between a node and an adjacent antinode is 0.59 cm. What is the microwave frequency?
