What else can I help you with?
Red light CANNOT cause an electron to be ejected from a potassium atom because of?
The energy of red light is lower than the energy required to remove an electron from a potassium atom. The energy required to remove an electron is called ionization energy, and red light does not have enough energy to surpass this threshold for potassium atoms.
What element emits a red light when an electron transition occures?
The element that emits red light when an electron transition occurs is typically hydrogen. This is due to the visible light spectrum associated with the specific energy levels in the hydrogen atom that produce red light when electrons move between them.
What characteristic of their an atom's light allows you to tell one atom from another?
first you must know what ROY G BIV is. that is the spectrum of visible light humans can see and it stands for Red Orange Yellow Green Blue Indigo Violet. the specific characteristic of light that allows you to tell one atom from another has to do with the fact that light travels in waves. each element gives off its own specific and unique light pattern and the different colors of visible light travel in different waves. the color red is the longest wave and violet is the shortest. so lets say hypothetically that you tested helium and you got red light, next you tested oxygen and you got yellow. this would indicate that the two atoms of the element are different because you got two different colors, and therefore two different wavelengths.
What color are the longest waves of light?
The longest waves of light are red. In the visible light spectrum, red light has the longest wavelength, which is around 620-750 nanometers.
What is the symbols in a street light?
The most common symbols on a street light are a red light to stop, a green light to go, and a yellow light to signify caution. Additionally, there may be pedestrian signals, such as a walking person or a hand, to indicate when it is safe to cross the street.
What does a red and greed light indicate when heading toward you at night?
A red light on the left and a green light on the right indicate that you are looking at the port (left) side of a boat that is heading toward you at night.
Is it correct to say he jumped a red light?
Yes, it is correct to say "he jumped a red light" to indicate that he ignored a traffic signal and did not stop when the light was red.
Which color light indicates towing?
Red lights indicate that someone in towing something. They could be blinking or just a red light.
Why is the red light on the headlamp illuminated?
The red light on the headlamp is illuminated to indicate that the rear brake is engaged or that there is an issue with the brake system.
Why is the bathroom red light flashing?
The red light in the bathroom is flashing to indicate a potential issue or emergency, such as a malfunction or a need for attention.
Red light CANNOT cause an electron to be ejected from a potassium atom because of?
The energy of red light is lower than the energy required to remove an electron from a potassium atom. The energy required to remove an electron is called ionization energy, and red light does not have enough energy to surpass this threshold for potassium atoms.
What does a red and green light seen at night indicate?
Sail boat is coming at you
Why does the red light come on?
The red light comes on typically to indicate a warning or error condition. In electronic devices, a red light may indicate a power issue, such as low battery or a hardware malfunction. In automotive settings, a red light may signal a critical problem with the vehicle that requires immediate attention. The specific reason for the red light coming on would depend on the context in which it is occurring.
What does a red and green light indicate when seen together at night?
Sail boat is coming at you
What does a red and green light indicate seen together at night?
Sail boat is coming at you
What does green and red light indicate when seen together at night?
Sail boat is coming at you
What does a red and a green light on a boat indicate when seen together at night?
The red light is on the port side of the boat, while the green light is an the starboard side. So, if the boat in front is showing a red light on the left and a green light on the right, it is going away from you.
