level questions: Visible light (HARD)

QuestionAnswer
Beams of electromagnetic radiation that travel in straight lines.Light Rays
How do light rays behave when they encounter surfaces?Light rays can be reflected off surfaces in different ways.
The bouncing back of light rays from a surface when they encounter it.Reflection
What are the two different ways light rays can be reflected?Specular reflection and diffuse reflection.
Reflection from a smooth, flat surface in a single direction, producing a clear image.Specular Reflection
What type of surface results in specular reflection?Smooth, flat surfaces.
Reflection or scattering of light rays from a rough or uneven surface, resulting in no clear image.Diffuse Reflection
What type of surface results in diffuse reflection?Rough or uneven surfaces.
The process by which light rays are dispersed or spread out in various directions when they encounter an uneven surface.Scattering
What happens during diffuse reflection?Light rays are scattered in various directions, resulting in no clear image.
A visual representation of an object formed by light rays that have been reflected, refracted, or diffracted.Image
What type of reflection produces a clear image?Specular reflection, such as the reflection in a mirror.
Electromagnetic radiation that is visible to the human eye, occupying a small portion of the electromagnetic spectrum.Visible Light
What is visible light?Electromagnetic radiation that is visible to the human eye.
The range of all possible frequencies of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.Electromagnetic Spectrum
What is visible light part of?The electromagnetic spectrum.
The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.Wavelength
What determines the color of light within the visible light spectrum?The wavelength of the light.
The number of complete wavelengths that pass a point in a given time, usually expressed in hertz (Hz).Frequency
How does the frequency of light relate to its color within the visible light spectrum?Red light has the lowest frequency, while violet light has the highest frequency.
Electromagnetic radiation that is visible to the human eye, typically ranging from about 400 to 700 nanometers in wavelength.Visible Light
What determines the color of objects as perceived by humans?The wavelengths of visible light that are absorbed, reflected, or transmitted by the object.
The process by which light is taken in and converted into other forms of energy by a substance.Absorption
What happens when an object absorbs certain wavelengths of light?It appears to have absorbed those wavelengths and may appear as a different color.
The process by which light bounces off a surface.Reflection
How does reflection contribute to the perception of color in objects?Objects reflect certain wavelengths of light, contributing to their perceived color.
The passage of light through a substance without being absorbed or reflected.Transmission
How does transmission affect the color of an object?Objects that transmit certain wavelengths of light may appear to have a particular color.
An object that predominantly reflects or transmits red light and absorbs other colors.Red Object
What happens when a red object reflects or transmits red light?It appears red to the human eye.
An object that predominantly reflects or transmits blue light and absorbs other colors.Blue Object
What happens when a blue object reflects or transmits blue light?It appears blue to the human eye.
An object that reflects all wavelengths of visible light equally.White Object
How does a white object appear to the human eye?It appears white because it reflects all colors of visible light equally.
An object that absorbs all wavelengths of visible light.Black Object
How does a black object appear to the human eye?It appears black because it absorbs all colors of visible light.
Optical devices that selectively transmit certain wavelengths or colors of light while absorbing others.Filters
What do filters do with regards to light?Filters only transmit certain wavelengths (and colors) of light while absorbing others.
The passage of light through a substance without being absorbed or reflected.Transmission
What happens to light when it passes through a filter?Only certain wavelengths (and colors) of light are transmitted while others are absorbed.
A filter that transmits predominantly red wavelengths of light while absorbing other colors.Red Filter
What type of light passes through a red filter?Only red light passes through a red filter.
A filter that transmits a combination of red, blue, and violet wavelengths of light while absorbing other colors.Magenta Filter
What colors of light pass through a magenta filter?Red, blue, and violet light pass through a magenta filter.
The process by which light is taken in and converted into other forms of energy by a substance.Absorption
What happens to the wavelengths of light that are not transmitted through a filter?They are absorbed by the filter.
Visible light that contains all wavelengths of the visible spectrum in equal amounts.White Light
What happens when white light is aimed at a filter?Only certain wavelengths (and colors) of light that match the filter's transmission properties will pass through, while others are absorbed.
