Color is the visual perception of different wavelengths of light. It is typically described by its hue, saturation, and brightness.
An oxygen meter, also known as a pulse oximeter, works by using light to measure the oxygen saturation of your blood. It emits light through your fingertip and detects how much is absorbed, which changes based on the level of oxygen in your blood. The device then calculates your oxygen saturation level and displays it on the screen.
Color is a visual attribute of objects determined by the light they reflect or emit. It is defined by three main characteristics: hue (the specific color, e.g., red, blue), saturation (the intensity of the color), and brightness (the lightness or darkness of the color). These characteristics combined create the wide range of colors we perceive in the world.
The three basic characteristics of color are hue (the name of the color, e.g. red, blue), saturation (the intensity or purity of the color), and brightness (the amount of light or darkness in the color).
The frequency of light that is reflected or emitted by an object. So, every frequency represent another colour. Not every frequency is visible for the human eye (e.g. infra red, ultra violet).
Color is the visual perception of different wavelengths of light. It is typically described by its hue, saturation, and brightness.
Photoreceptors detect visual stimuli, specifically light. They are cells in the retina of the eye that are sensitive to different wavelengths of light and help to initiate the process of vision.
No. It is the retina at the back of the eyeball that has the cones and rods that receive stimulus from light and send it to the brain for processing into visual images.
It is a response called phototropism, where the plant grows towards light as a result of the stimulus of light perception.
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
i think it's plants. plants are stimulus to light ans as a result always grow in the dierction of light...
An example of a physical stimulus is light, which can trigger sensory responses in organisms. For instance, when light enters the eye, it stimulates photoreceptor cells in the retina, leading to visual perception. Other examples include sound waves that cause vibrations in the air, which can be detected by the ear, and heat, which can be felt through the skin.
The stimulus in the pupil reflex would be light

Tropism is the movement of a plant away from or toward a stimulus. The most easily found example of tropism is a plant's response to light. Plants tend to grow toward the light. This tendency is called 'phototropism'.
