Laser light is different in many ways. These are the biggies.
a) Laser light is almost monochromatic. Because it is created by exciting a specific substance to emit photons, the light emitted by the source is almost all one specific wavelength. The light from a flashlight contains all of the colors in the spectrum, forming "white light".
b) Laser light is very coherent. This means that the waves leaving the laser remain in phase for a very long time. Light from a flashlight is not coherent. As a result, a laser can project a distinct beam of light much farther than a flashlight.
c) Laser light is directional. This means that the beam of light being emitted does not spread much with distance. Hence it can still appear as a point of light many meters away from the source. A flashlight beam will quickly spread the further it is viewed from the source.
Because of these fundamental properties, lasers are an excellent experimental device.
What else can I help you with?
What tool is used to help determine the colors of light emitted by a flashlight?
A spectrophotometer is typically used to determine the colors of light emitted by a flashlight. This device can measure the spectrum of light emitted and provide information about the specific colors present.
What's the wavelength of the light emitted by the laser?
The wavelength of the light emitted by the laser is typically in the range of 400 to 700 nanometers.
What colors of light are emitted by a flashlight?
A flashlight typically emits white light, which is a combination of different colors in the visible spectrum. The light source in a flashlight, such as an LED or an incandescent bulb, produces a broad spectrum of colors that combine to create white light.
What tool could help me know witch colors of light are emitted by my flashlight?
You could shine your flashlight through a prism- the prism will split the light into all the colors it was formed from. If your flashlight gives off standard white light, you don't have to use a prism because all white light is formed from all the colors of the rainbow.
Wendy wants to know which colors of light are emitted by her flashlight. Which tool could help her?
A spectrophotometer would be helpful for Wendy to determine the colors of light emitted by her flashlight. This device can separate light into its different wavelengths and identify the specific colors present.

How are a laser beam and flashlight beam alike and different?
A laser is L ight A mplification by S imulated E mission of R adiation a flashlight is pretty much a lightbulb that in some cases with the design of it can be amplified They're both alike as they both consist of photons. They're different because the laser only emits one wavelength, while a flashlight emits a mix of wavelengths. They're also different because in the light from the laser all the light waves are emitted in synch(crests and troughs appears simultaneously) while from the flashlight they appear every which way

Which type of light does a flashlight produce?
A flashlight typically produces white light, which is a combination of all visible wavelengths of light. The light is usually emitted from a light bulb or LED located within the flashlight.
How a beam of laser light is different than the beam of light produced by a flashlight?
It does depend on the kind of laser, but the main difference is that a laser emits a focused beam of light of the same wavelength (i.e. color) while a flashlight emits light of many different wavelengths, and 'beams' this light by reflecting it using a concave mirror built into it behind/around the bulb.
Which part of a flashlight is the output?
The bulb is the output. It is what illuminates the dark.
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.
Stored energy in a flashlight and batteries becomes light energy when the flashlight is turned on?
Yes, when a flashlight is turned on, the stored chemical energy in the batteries is converted into electrical energy, which then gets converted into light energy by the bulb. The light energy is what we perceive as the beam of light emitted from the flashlight.
Why is brightness of the light emitted by a flashlight decreases as the flashlight moves farther away?
The brightness of the light emitted by a flashlight decreases as it moves farther away due to the spreading out of the light waves over a larger area, leading to a decrease in the intensity of light at any given point. This is known as the inverse square law, where the intensity of light decreases by the square of the distance from the source.
