Q:

What is the bending of light called?

A:

Quick Answer

The bending of light, sound or heat waves is known as refraction. Refraction occurs when a light wave, heat wave or sound wave moves from one medium to another.

Full Answer

When a wave travels from one medium to another with a different density, the velocity of the wave changes. This change in velocity changes the direction of the wave, making it bend. The bend occurs at the interface, the point at which the medium changes. Though the velocity changes, the frequency of the wave remains constant. The change in direction can be calculated using Snell's law and is frequently used in optics development.

  • Q:

    What is the reflection of sound?

    A:

    When sound waves strike a surface, they reflect off of that surface and can return to the source of the sound as an echo. To a listener, this may be identical to the original sound, just delayed and possibly distorted by its path through the air. If the echo arrives quickly enough, it may seem to be part of the original sound, forming a reverberation instead of an echo.

  • Q:

    How are radio waves detected?

    A:

    Radio waves are detected using electrical circuits that receive these electromagnetic signals in an antenna, and then the radio frequencies are modulated through capacitors before emerging as sound in a speaker. Radio waves are normally less than a kilohertz long up to 20 gigahertz. Since humans cannot hear these frequencies, radio signals are often translated into sounds by electrical devices.

    What are basic ultrasound physics?

    A:

    Ultrasound consists of a series of extremely high-frequency waves of sound, which may be bounced off of objects to form an image in three dimensions, according to ICU Sonography. Ultrasound scanners are used to noninvasively scan the interior of many objects including the human body.

    What is the difference between pitch and volume?

    A:

    The difference between pitch and volume is that pitch is determined by the frequency that sound waves vibrate at while volume measures how loud or soft sound is. Combined with timbre, pitch, measured in hertz, and volume, measured in decibels, comprise the three components of sound.
