What else can I help you with?
Light frequency from an incandescent lamp depends on what?
The light frequency from an incandescent lamp depends on the temperature of the filament. As the filament heats up, it emits a broad spectrum of light that includes all visible frequencies.
A luminous object is an object that?
It means it radiates photons. This can theoretically be at any frequency. Heat, visible light, infra-red, X-rays etc. But it's normally a term used to describe visible light radiation.
What is the difference between a black light bulb and white light bulb?
A black light bulb emits ultraviolet (UV) light, which is typically invisible to the human eye but can cause fluorescent materials to glow. A white light bulb emits visible light across a spectrum of colors.
What type of light does photosphere emit?
The photosphere emits the visible light from the sun.
Does a nebula have no light of its own?
It does not have visible light of its own, that lite is provided by the shine of the stars in it and or around it.
Are you able to see an object when it emits or reflects one or more visible light frequencies?
Yes.
Why do object appear white?
A white object emits light in all/most of the visible spectrum evenly.Because it reflects all the light back.
How many different frequencies does the sun have?
The sun emits a wide range of frequencies across the electromagnetic spectrum, but human eyes can only detect a small portion known as visible light. In addition to visible light, the sun also emits ultraviolet, infrared, and radio frequencies, among others.
If an object emits or reflects light?
It can be seen by the eye.
How does the tempeature of an object influence the radiation it emits?
The temperature of an object affects the amount and type of radiation it emits. As temperature increases, the object emits more radiation and at higher frequencies. This relationship is described by Wien's displacement law and the Stefan-Boltzmann law.
Is color a property of an object?
Yes, color is a property of an object that is determined by the way the object reflects or emits light at different wavelengths.
Why don't we use visible-wavelength telescopes to locate neutron stars?
A neutron star emits most of its energy at higher frequencies.
What is black made out of?
A object appears black when it reflects or emits no visible light. True black is very uncommon because almost no substance can completely absorb light. http://en.wikipedia.org/wiki/Black
What is an called when the object glows when it is heated?
An object that glows when heated is called incandescent. This phenomenon occurs when the object's temperature increases to the point where it emits visible light.
Is color a property of an object?
Yes. The colour of an object is determined by what frequenc(y/ies) of electromagnetic wave it emits in the visible spectrum. The colour of an object is a physical property of that object.
Why is the statement the color of an object depends on the wavelengths of light it absords inaccurate?
...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
do moon reflects light or emits?
it reflects
