TYPICAL NUMERIC QUESTIONS FOR PHYSICS I REGULAR QUESTIONS TAKEN FROM CUTNELL AND JOHSNON WAVES (5) Science concepts. The student knows the characteristics and behavior of waves. The student is expected to: (A) examine and describe a variety of waves propagated in various types of media and describe wave characteristics such as velocity, frequency, amplitude, and behaviors such as reflection, refraction, and interference; (B) identify the characteristics and behaviors of sound and electromagnetic waves; and (C) interpret the role of wave characteristics and behaviors found in medicinal and industrial applications. 1.The speed of sound in a certain metal block is 3.00 × 10 3 m/s. The graph shows the amplitude (in meters) of a wave traveling through the block versus time (in milliseconds). What is the wavelength of this wave? A) 0.5 m B) 1.5 m C) 3.0 m D) 4.0 m E) 6.0 m 2. What is the wavelength of a wave with a speed of 12 m/s and a period of 0.25 s? A) 0.25 m B) 1.5 m C) 3.0 m D) 24 m E) 48 m 3. A wave has a frequency of 58 Hz and a speed of 31 m/s. What is the wavelength of this wave?
