Waves For Detection And Exploration (physics Only) (ht Only) (GCSE Physics)

Intensity I of a wave is proportional to which combination of wave properties?

A wavefront diagram shows wavefronts compressed on one side of a moving source. What does this indicate for an observer on the compressed side?

Why does refraction not occur when a ray strikes a rectangular glass block at normal incidence?

A subsurface feature is detected by reflected waves arriving later than expected. Which change in the medium most likely causes the reflection arrival to be delayed?

An ultrasonic pulse is sent vertically down into water and the echo from the seabed returns 0.40 s later. If the speed of sound in seawater is 1500 m/s, how deep is the seabed?

A ground-penetrating radar (GPR) pulse has a round-trip time to a buried object of 1.0 × 10^-8 s in soil where pulse speed ˜ 1.5 × 10^8 m/s. What is the burial depth?

In seismic exploration, why do S-waves not travel through the outer core of the Earth?

Which statement correctly distinguishes P-waves and S-waves produced by earthquakes?

Which detection method is most appropriate for mapping shallow archaeological ruins a few meters below ground with high spatial detail?
