What is the physical dimension of light and sound that determines brightness and loudness?
The physical dimension that determines the brightness of light is intensity, measured in units like watts per square meter. For sound, the physical dimension that determines loudness is amplitude, measured in units like decibels. Both intensity and amplitude correlate with the perceived brightness or loudness of light and sound, respectively.
A light waves brightness depends on the?
A light wave's brightness depends on its amplitude, which determines the intensity of the wave. The greater the amplitude, the brighter the light wave will appear.
What does amplitude determine in light?
amplitude will determine the brightness in light or the loudness in sound.
What determines brightness of the light wave?
The brightness of a light wave is determined by its amplitude, or the height of the wave. A larger amplitude means a brighter light wave, while a smaller amplitude results in a dimmer light wave. Brightness can also be affected by factors such as the distance the light travels and the materials it interacts with.
What determines the brightness of a light bulb?
The brightness of a light bulb is determined by the amount of electrical energy it receives, which affects the intensity of the light produced. A higher wattage bulb will generally be brighter than a lower wattage bulb.

What does the amplitude of a light wave determine?
The amplitude of a light wave shows the light's brightness relative to waves of similar wavelength.
What are two factors that affect the brightness of the light?
Two key factors that affect the brightness of light are intensity and distance. The intensity of the light source determines how much light is emitted; a higher intensity results in greater brightness. Additionally, as the distance from the light source increases, the brightness decreases due to the inverse square law, which states that light spreads out over a larger area, reducing its intensity per unit area.
How is a shadow affected by the brightness of the light source?
The brightness of the light source determines the intensity of the shadow. A brighter light creates a sharper and more defined shadow, while a dimmer light results in a softer and less defined shadow. Additionally, the size of the light source can also affect the sharpness of the shadow edges.
What does the amplitude of a light wave determine your perception of?
The amplitude of a light wave determines the brightness or intensity of the light that you perceive. A higher amplitude corresponds to brighter light, while a lower amplitude corresponds to dimmer light.
When the amplitude decreases what happens to the frequency?
When the amplitude decreases, the frequency remains constant. Amplitude and frequency are independent of each other in a wave. The frequency determines the pitch of the sound or the color of light, while the amplitude determines the intensity or loudness of the sound or brightness of light.
What is brightness as sound is to light?
Loudness is to brightness as sound is to light.
Why does the length of the wires does not matter when lighting a light bulb?
The length of the wire does not typically affect the brightness of the light bulb because the resistance in the wire remains fairly constant regardless of its length. The resistance of the wire is what actually determines the amount of current flowing through the circuit, which in turn affects the brightness of the light bulb.
