Which of these external stimuli produces growth of the plant toward light?
The stimulus that produces growth of the plant toward light is called phototropism. It is caused by the presence of blue light, specifically light in the 440-470nm wavelength range, which is detected by the plant's photoreceptor molecule called phototropin. This photoreceptor triggers a signaling pathway that stimulates cell elongation on the shaded side of the plant, resulting in growth towards the light source.
What color of visible light has the longest wavelength?
Red is the longest wavelength of visible light
Which type of visible light has the longest wavelength?
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
What is growth movement of a plant toward the light called?
phototropism.
Can light have a single wavelength?
Yes, light can have a single wavelength. A laser generates a coherent beam of light. It's all one frequency, i.e., it's all the same wavelength.
When a star or galaxy moves quickly toward an observer the light it emits will appear?
It will be "blue-shifted". That is, the wavelength of the light will appear to be shorter and so more blue.
What is an increase in the wavelength of light as a galaxy moves away from earth?
Red Shift
What is a wavelength of light that can be seen called?
It is literally called visible light..
An apparent shift in the wavelength of light emmited by a light source moving toward or away from an observer is known as?
The Doppler Effect.
What is a light having one wavelength called?
At a single wavelength, it is called monochromatic
How important is red shift to your understanding of the universe?
Redshift happen when light seen from the object that is moving away is proportionally increased in wavelength (i.e shifted toward the red end of the spectrum) . Thus red shifts relates that further the galaxy ( outside or inside the local cluster ) more it is red-shifted (i.e greater the wavelength ) than the closer galaxy and it explain the expansion of our universe , further the galaxy more fast it moves away from us .
What would evidence of a galaxy moving toward Earth?
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
What is the number of centimeters between waves of light?
The measure of a light's frequency is called wavelength.
What does the increase in wavelength of light from a galaxy mean?
This is usually expressed, equivalently, as a reduction in frequency. It means that the galaxy moves away from us. For more information, you may want to read about redshift.
Which of these external stimuli produces growth of the plant toward light?
The stimulus that produces growth of the plant toward light is called phototropism. It is caused by the presence of blue light, specifically light in the 440-470nm wavelength range, which is detected by the plant's photoreceptor molecule called phototropin. This photoreceptor triggers a signaling pathway that stimulates cell elongation on the shaded side of the plant, resulting in growth towards the light source.
What is longer than visible wavelength called?
Infrared has a longer wavelength, and a lower frequency, than visible light.
How can astronomers determine whether star is moving toward or away from earth?
Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.
