How is bulb useful?
it's useful for light and safety.
How is the light bulb a useful invention?
The light bulb is useful because it lights up places!
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
What useful energy is in a light bulb?
The useful energy in a light bulb is the light that it emits. When electricity flows through the filament of a light bulb, it produces light energy that we can see and use for illumination.
Useful and non-useful energy transfers for coal?
Useful: Energy Light Sound Non-Useful: Electricity C02
What useful energy comes out of a light bulb?
A light bulb emits light energy, which is useful for illuminating a space and providing visibility. Some light bulbs also produce heat energy, although this is often considered a byproduct rather than a primary source of useful energy.
What is the color of light that is the least useful to plans during photosynthesis?
red and blue light is most useful. But others are not.
What is the useful energy of a light bulb?
The useful energy of a light bulb is the light it emits, which is used for illumination. This is the intended function of the light bulb, as it allows us to see and perform tasks in dark environments.
How are reflective properties of light useful?
theyre not
Is light energy useful to people?
Yes.
What two wavelengths of light are least and most useful to photosynthesis?
Green light is the least useful wavelength for photosynthesis because it is mostly reflected by chlorophyll. Red and blue light are the most useful wavelengths for photosynthesis as chlorophyll absorbs them most efficiently for the process.
How do chemicals stains light microscopes more useful?
Chemical stains make light microscopes more useful by showing specific structures in a cell.
