To solve this problem we will apply the given relationship between wavelength, speed and frequency as well as the use of kinematic equations of motion description.
The wavelength is directly proportional to the speed and inversely proportional to the frequency, in other words,
Where
v = Velocity
f = Frequency
Speed is not given but if the distance traveled in a certain time, that is
Replacing
Substituting this value at our first equation we have
Therefore the wavelength of the seismic wave is 2000m
Answer:
Wavelength = 489.52 nm
Explanation:
Given that the wavelength of the light = 633 nm
The time taken by the light in unknown liquid = 1.38 ns
Also,
1 ns = 10⁻⁹ s
So, t = 1.38 × 10⁻⁹ s
Also,
Distance = 32.0 cm = 0.32 m ( 1 cm = 0.01 m)
<u>So, speed of the light in the liquid = Distance / Time = 0.32 / 1.38 × 10⁻⁹ m/s = 2.32 × 10⁸ m/s</u>
Frequency of the light does not change when light travels from one medium to another. So,
So,
<u>Wavelength = 489.52 nm</u>
B and C because an earthquake does not directly affect gravity, and precipitation doesn’t fall, it is water surfacing
