# What does amplitude affect in waves?

## What does amplitude affect in waves?

As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder. Relative sound intensities are often given in units named decibels (dB).

## What factors affect the speed of a wave?

The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f). Certain conditions make the following calculations easy. speed is constant in a given medium.

## Is amplitude directly proportional to wave speed?

The amplitude of a wave is directly proportional to its speed.

## Does amplitude affect wave frequency?

The amplitude and the frequency of a wave are independent of each other. The amplitude and the frequency of a wave are equal. The amplitude decreases with an increase in the frequency of a wave.

## What does amplitude of a wave measure?

Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

## How is wave speed calculated?

Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

## Can you survive a mega tsunami?

The short answer is no. This is one of those gleefully alarmist, CGI-stuffed documentaries designed to make us sleep less peacefully in our beds. You see, regular tsunamis (or tidal waves, as we used to know them) are caused by ocean-floor earthquakes. They can, of course, cause colossal damage and loss of life.
