What wavelengths of light does each pigment absorb?
Chlorophyll a absorbs mainly blue and red wavelengths of light, with peaks around 430nm and 680nm. Chlorophyll b absorbs blue and orange light, with peaks around 450nm and 640nm. Carotenoids absorb mainly in the blue-green range, around 450-550nm.
At what wavelength is photosynthetic activity the greatest?
Photosynthetic activity is greatest at wavelengths of red and blue light, around 400-700 nanometers.
How many light-sensitive cells does a house fly have?
A house fly has around 3,000 ommatidia, each containing 6-8 photoreceptor cells, totaling roughly 18,000-24,000 light-sensitive cells.
What is the function of the light-sensitive part of the eye in the process of vision?
The light-sensitive part of the eye, called the retina, detects light and converts it into electrical signals that are sent to the brain. This process allows us to see and interpret the world around us.
What does sensitivity mean in mrs gren?
In terms of MRS GREN, sensitivity refers to the ability of an organism to respond to changes or stimuli in its environment. It involves how an organism reacts to external factors and adjusts its behavior for survival.
What is electromagnetic frequencies to which our eyes are sensitive?
Our eyes are sensitive to electromagnetic frequencies in the visible light spectrum, which includes wavelengths ranging from approximately 400 to 700 nanometers. This range of wavelengths is what allows us to perceive colors and see the world around us.
Can kids with asthma be around a puppy?
Asthmatics are sensitive to many contaminants in the environment. Not all asthmatics are sensitive to exactly the same things. Cats are usually more trouble than dogs.
What measurement is used for the wavelengths of color?
The measurement used for the wavelengths of color is typically in nanometers (nm). Each color has a specific range of wavelengths in the visible spectrum, with red having longer wavelengths around 700 nm and violet having shorter wavelengths around 400 nm.
What are some of the characteristic of chromatic aberration?
As different wavelengths of light are refracted slightly differently through a lens, a prismatic effect, or "rainbow" occurs around each point-source of light, usually worst at the fringes of the viewing field, and least near the center.
What is an instrument for viewing around?
An instrument for viewing around is typically a type of optical device designed to observe the surrounding environment. Examples include binoculars, which magnify distant objects, and periscopes, which allow users to see over obstacles. These instruments enhance visual perception and can be used in various contexts, such as nature observation, military applications, or underwater exploration.
Are human eyes most sensitive to the red or blue or yellow green part of the visible light spectrum?
Human eyes are most sensitive to the yellow-green part of the visible light spectrum, particularly around the wavelengths of 555 nanometers. This sensitivity is due to the peak response of the cone cells in our retinas, which are responsible for color vision. While we can perceive red and blue light, our visual system is optimized for detecting greenish tones, which is important for activities like identifying foliage and other natural elements in our environment.
What is the range of frequencies are our eyes sensitive to?
Human eyes are sensitive to light in the electromagnetic spectrum, specifically within the range of approximately 380 to 750 nanometers. This range corresponds to visible light frequencies from around 430 terahertz (THz) to 790 THz. Within this spectrum, different wavelengths correspond to different colors, with violet at the lower end and red at the upper end.
How do we see the color yellow?
We see the color yellow when light enters our eyes and stimulates special cells called cones in the retina. These cones are sensitive to different wavelengths of light, and when they are stimulated by light with a wavelength around 570-590 nanometers, we perceive the color yellow.

What wavelengths do plant absorb most?
Plants primarily absorb red (around 660 nm) and blue (around 450 nm) wavelengths of light for photosynthesis. These wavelengths are most effective in driving the process of converting light energy into chemical energy. Green light (around 550 nm) is not absorbed as efficiently, which is why plants appear green to us.
What is equivalent to the size of microwave wavelengths?
Microwave wavelengths fall in the range of approximately 1 millimeter to 1 meter. This range of wavelengths is equivalent to frequencies from around 300 MHz to 300 GHz. The size of microwave wavelengths is often used in various applications such as microwave ovens, radar systems, and telecommunications.
What type of electromagnetic waves does the human eye see as the colors redblue or green?
The human eye can see visible light, which consists of electromagnetic waves with wavelengths ranging from approximately 400-700 nanometers. Within this range, red light has longer wavelengths (around 620-750 nm), green light has mid-range wavelengths (around 495-570 nm), and blue light has shorter wavelengths (around 450-495 nm).
