What is light bulb filament element and symbol?
A light bulb filament is a coiled wire inside the bulb that heats up and produces light when an electrical current passes through it. The symbol for a light bulb filament is usually represented as a zigzag line inside a circle.
What is a similarity in the line spectrum of mercury and the spectrum of the fluorescent bulb?
A fluorescent lamp contain mercury so the identities of spectrum are normal.
What is unique about the spectrum obtained for a fluorescent light?
The spectrum obtained for a fluorescent light is unique in that it produces a discrete line spectrum with distinct peaks at specific wavelengths, rather than a continuous spectrum. This is due to the combination of the phosphor coating in the tube and the mercury vapor emitting specific wavelengths of light when excited.
What filament is connected to the Z line thick or thin?
The filament connected to the Z line in a muscle cell is thin filament, specifically actin filament. Thick filaments (myosin) are connected to the M line in the sarcomere.
Is the spectrum for the incandescent light a continuous spectrum or a line spectrum?
incandescent bulb is equivalent to white light, i.e it has all the seven wavelengths of light. therefore when passed through a prism it is disperses into all the seven wavelengths WITHOUT ANY SPACES OR BOUNDARIES and are obtained on the screen as a CONTINUOUS SPECTRUM.
Why isn't the resistance of a torch bulb a straight line on a graph?
The resistance of a torch bulb is not a straight line on a graph because its resistance changes with temperature. As current flows through the filament, it heats up and its resistance increases due to the temperature coefficient of the material, typically tungsten. This non-linear relationship results in a curved graph when plotting current versus voltage, demonstrating that the bulb does not obey Ohm's Law under all conditions. Thus, the behavior of the filament varies with changes in electrical current and temperature.
What is a line spectrum used for?
The line spectrum is usually used to sort out the atomic fingerprint as the gas emit light at very specific frequencies when exposed to the electromagnetic waves. The electromagnetic waves are usually displayed in form of the spectral lines.
Which filament is anchored to the middle of the sarcomere?
The m line
Why are filaments of bulb coiled?
The filaments of a light bulb are coiled to increase their resistance, which in turn generates heat and light when an electric current passes through them. The coiled shape allows for a longer filament to be contained within a compact space, maximizing the surface area for heat and light production. Additionally, the coiled shape helps to evenly distribute the heat across the filament, preventing hot spots that could lead to premature failure.
How is energy transferred from the battery to the bulb of a torch or flashlight?
Energy is transferred from the battery to the bulb of a torch or flashlight through a closed circuit. When the battery is connected to the bulb, it provides electrical energy to the filament in the bulb, which then converts the electrical energy into light energy through the process of electrical resistance. This light energy is what produces the glow in the bulb.
Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
What is the difference between the spectrum of the light bulb and the spectra of gas tubes?
The spectrum of a light bulb is continuous, meaning it covers a broad range of wavelengths with no distinct lines. Gas tubes emit light at specific wavelengths called emission lines, producing a line spectrum with discrete colored lines. This difference is due to the way light is generated in each source.
