Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What formula is used to calculate the velocity of radar waves in a medium?
- v = c/ϵr
- v = ϵr × c
- v = c + ϵr
💡 Hint: Think about how the dielectric affects speed.
Question 2
True or False: The one-way travel time is always half of the two-way travel time.
- True
- False
💡 Hint: Remember the definition of two-way travel time.

Question 1
A GPR measures a two-way travel time of 200 ns with a dielectric constant of 9 in a wet soil medium. Calculate the depth to the object.
💡 Hint: Don't forget to convert time from ns to seconds before calculating.
Question 2
If a material's dielectric constant increases, how might this affect the GPR depth accuracy? Explain your reasoning.
💡 Hint: Consider the fundamental relationship of dielectric constant to speed.
