Does the amount of light increase if more and more flashlight beams are combined into one beam?
I'm not sure what you mean by 'the amount of light', or how you might plan to 'combine' several beams. When more flashlights shine on a surface, the intensity of illumination on the surface increases.
Is putting a flashlight in a tank of water reflection or refraction?
Neither. it is getting a flashlight wet. The beam of light from the flashlight will refract when exiting the tank (and refract several times if going through a glass wall of the tank). If the tank wall is smooth enough of a material with enough of a difference in optical density and the flashlight beam hits the wall at a small enough angle there will be total internal reflection.
Why laser produces Gaussian beam?
A laser produces a Gaussian beam because of the diffraction effect of the laser beam passing through an aperture. The electric field distribution of the beam follows a Gaussian shape due to the wave nature of light. This results in a beam that has a bell-shaped intensity profile with a narrower central peak and gradually decreasing intensity towards the edges.
How are a laser beam and a flashlight beam alike and different?
A LASER, or Light Amplification by Simulated Emission of Radiation, and is made by causing a particular substance to emit photons, almost all of which are one wavelength. A flashlight, however, uses a light bulb, which emits light due to the filaments, and will spread out. Both, however, are forms of light.
What will increase the effective energy of the xray beam?
increasing its frequency
If beam area decreases the intensity will?
Increase
Why the intensity of the light in a flashlight beam decreases as the flashlight moves farther away?
Because the constant amount of light that the flashlight produces is spread out over a larger area when it's farther away, so the intensity at every point is less. Light decreases inversely to the square of the distance.
What is the geometric figure of a flashlight beam?
A flashlight beam is like a acute
What happens to the beam of a flashlight when it hits a mirror?
When the beam of a flashlight hits a mirror, it is reflected.

What is the output of a flashlight?
A beam of light.
What is the output in a flashlight?
A beam of light.
How harmful can a flashlight be?
If the flashlight is turned on and direct beam to eyes, it is harm to eyes.
What is considered the output of a flashlight?
A beam of light.
What does the intensity of a beam of em radiation mean?
The intensity of a beam can be measured by the power contained in a square metre cross-section of the beam. For example the Sun's light has an intensity of about 1400 watts per square metre.
How did the filter affect the white flashlight beam?
Filter is fixed on the head of flashlight to change light color. If you use red filter, the beam will be in red light.
What is the luminance of Streamlight flashlights?
On Amazon, there is a Streamlight flashlight, model 74301, that has five different settings and three different types of luminescence. On high, the peak beam intensity is 10,000 candela -160 lumens. On medium, the peak beam intensity is 5000 candela - 80 lumens; and on low, the peak beam intensity is 2500 candela - 40 lumens. According to the website Learning Centre, Streamlight uses gas-filled lamps that provide a high output and a more natural light.
