If the detector is capturing 9 107 photons per second at this wavelength what is the total energy of the photons detected in one hour?

You can easily calculate the energy that the photon detects per second by using the relation E=hc/w where E is energy in Joules, h is Planck's constant, c is the speed of light, and w is the wavelength.

Hope this helps.

Photons with the highest energy have?
highest frequency / shortest wavelength / same speed as all other photons.
All of its output energy is absorbed in a detector that measures a total energy of 0.53 J over a period of 32 s How many photons per second are being emitted by the laser?
Not enough information. Different photons have a different amount of energy, so you need some information about the photons' frequency, or alternately, their wavelength.
The color of light is determined by its?
Wavelength, or alternatively its frequency.
Photons of light?
... have roughly double the energy of photons of red light, because their frequency is roughly double the frequency of red-light photons. (That also means that their wavelength is roughly half the wavelength of red-light photons, but this fact doesn't help the current discussion at all.)
What is monochromatic source?
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.

Why are the photons that emerge from the Sun's surface visible-light photons and infrared-light photons rather than gamma-ray photons?
Photons do not come in different types like infared-photons etc. they are just the wavelength that the photons are at and nuclear fusion just happens to emit photons at a particular wavelength
What creates the phenomenon known as the red shift?
The expansion of space in all parts of our Universe. When a group of photons leave an object (like a super-nova in a distant galaxy), they have a certain wavelength, and a certain distance between the first photons from that super-nova and the last such photons. During their travel, the expansion of space causes the wavelength of the photons to increase (even if they interact with no matter whatsover in their travels), as well as the distance between the first photons to leave and the last photons to leave. If these photons travel for enough time (say, a few 100 million to a few billion years) before they reach a detector on our Earth, the increase in wavelength AND the distance between the first and last photons becomes measurable. The photons have a wavelength longer than they "should" have, and the time between the first photons to arrive and the last to arrive will increase. The increase in wavelength, as well as the increase in time for the super-nova to last, will be as predicted by Hubble's Law.
What is the longest wavelength photon?
There is no longest wavelength for photons. It can be arbitrarily long.

How does the amount of energy in the light changes as the wavelength increases?
The energy of the photons decreases as the wavelength increases
How does a plant frow in artificial lighting?
Same way it grows in sunlight. Photons of light at the right wavelength impact the pigment chlorophyll, excite and electron from the pigment which then enters photosystem II. Photons of the correct wave length are photons of the correct wavelength and the plant does not care what the source is of these photons.
A photon of wavelength 3000 A is absorbed by a gas and remitted as two photons One of the photons is red 7600 A What is the wavelength of the other photon?

Wavelength, energy, color (if visible).
