Final answer:
The frequency is 8 Hz and the amplitude cannot be determined in decibels.
Step-by-step explanation:
To find the frequency in Hertz (Hz), we can use the formula: frequency = 1 / period. In this case, the period is given as 1/8 of a second, or 0.125 seconds. Therefore, the frequency would be:
frequency = 1 / 0.125 = 8 Hz.
To find the amplitude in decibels (dB), we first need to understand that decibels are a measure of sound intensity, not wave amplitude. The amplitude of a wave is a measure of its maximum displacement from equilibrium. Therefore, we cannot directly convert wave amplitude to decibels.
In conclusion, the frequency is 8 Hz and the amplitude cannot be determined in decibels.
