Terry jumps up and down on a trampoline with a frequency of $1.5 \mathrm{~Hz}$. What is the period of Terry's jumping?

Step 1 ：Given frequency (f) = 1.5 Hz

Step 2 ：To find the period (T), use the formula: T = \(\frac{1}{f}\)

Step 3 ：T = \(\frac{1}{1.5}\) = \(\frac{2}{3}\) = 0.67

Step 4 ：\boxed{\text{Final Answer: The period of Terry's jumping is approximately 0.67 seconds.}}
