Given information
Given values:
The incidence angle,
The beginning of rock,
Rock's final act,
Formula used:
(1) The elastic modulus and density of the rock determine the wave speed for the rock.
where is the rock's elastic modulus
The rock's density.
(2)According to the law of refraction:
Where is the refraction angle and is the incidence angle.
is the wave's speed in the second medium (second rock), and is the wave's speed in the first medium (first rock)
Step-by-step explanation
Step 1.
The law of refraction,
