The second heart sound (S2) occurs after the T wave because it corresponds to the closure of the aortic and pulmonic valves in the heart. The T wave represents ventricular repolarization, which happens after ventricular contraction and ejection of blood through the aortic and pulmonic valves. The closure of these valves generates the S2 sound.

How to find the frequency of a sound wave?
To find the frequency of a sound wave, you can count the number of complete cycles of the wave that occur in one second. This is typically measured in hertz (Hz).
What two terms characterize a sound wave?
Frequency and amplitude characterize a sound wave. Frequency refers to how many cycles of the wave occur per second, measured in Hertz, while amplitude refers to the height of the wave and relates to the sound wave's intensity or volume.
What does the frequency of a wave measure?
The frequency of a wave measures the number of complete cycles of the wave that occur in one second. It is typically expressed in hertz (Hz) and is directly related to the pitch of sound waves or the color of light waves.
Is sound transverse or longitudinal in nature?
Sound is a longitudinal wave, meaning that the vibrations occur in the same direction as the wave travels.
Is frequency how loud something is?
No, frequency refers to the number of cycles of a wave that occur in a second and is measured in Hertz (Hz). Loudness is typically measured in decibels (dB) and is related to the amplitude of a sound wave. So, frequency and loudness are two different properties of sound.

Does the first heart sound occurs at the same time as the P wave of the electrocardiogram?
No, the first heart sound (S1) occurs at the start of ventricular systole when the atrioventricular (AV) valves close, while the P wave on an electrocardiogram represents atrial depolarization. So, they do not occur at the exact same time.
Is sound transverse or longitudinal in nature?
Sound is a longitudinal wave, meaning that the vibrations occur in the same direction as the wave travels.

I have no idea:P
How many waves occur in a given time?
The number of waves that occur in a given time period depends on the frequency of the wave. The frequency is defined as the number of complete wave cycles that occur in one second and is measured in hertz. For example, if a wave has a frequency of 10 Hz, it means that 10 complete wave cycles occur in one second.
What is the frequency of a sound wave that has thirty compressions in one second?
The frequency is 30 per second, or 30 'Hertz'.
What is meant by intensity of sound how it is different from loudness?
loudness is the magnitude of wave of sound(the highest point reached by the wave). intensity is frequency of sound (that's how much a wave vibrates in 1 second)
How do sound waves reflection occur and what factors influence the reflection of sound waves?
Sound wave reflection occurs when a sound wave hits a surface and bounces back. The factors that influence the reflection of sound waves include the angle of incidence, the nature of the surface, and the frequency of the sound wave.
Can Echoes occur underwater If so how?
Yes, echoes can occur underwater. When a sound wave hits an object, such as the seabed or a submerged object, the sound wave bounces off and returns to the source, creating an echo. The depth and composition of the water, as well as the frequency of the sound wave, can affect the strength and clarity of the echo.
