A Wave Has an Amplitude of 0

question 27

Multiple Choice

A wave has an amplitude of 0.35 m, a frequency of 1.05 × 10⁶ Hz, and travels in the positive x direction at the speed of light, 3.00 × 10⁸ m/s. Which one of the following equations correctly represents this wave?

• A)y = 0.35 sin (6.60 × 10⁶t - 0.022x)
• B)y = 0.35 sin (6.60 × 10⁶t + 0.022x)
• C)y = 0.35 sin (286t - 1.05 × 10⁶x)
• D)y = 0.35 sin (286t + 1.05 × 10⁶x)
• E)y = 0.35 sin (1.05 × 10⁶t + 3.00 × 10⁸x)
