Can scientists analize the elements of a star?
Scientists can assess which elements are present in the star, by looking at the light it gives off and breaking this light down into the different colours that make up the total colour. They look at the spectrum given off. The different elements present in the star cause different light wavelengths (or colours) to be emitted.
What does an universal indicator tell you about an acid that litmus doesn't?
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
How scientist discovered that start were made up of hydrogen?
Probably by using a spectrometer, analyzing the light for the colour makeups that identify the different elements uniquely. Stars are made of both Helium and Hydrogen, they are in constant fusion which gives light and heat to our planet, the light can be broken down into different "Wavelengths" which are identified by colour, ranging from IR(Infrared) to UV(UltraViolet) and the rainbow of colours that are visible to the naked eye are between those, hydrogen particles release their own unique combination of these colours in the light they produce.
Chlorophyll is a green pigment because it absorbs only the green part of the visible light spectrum?
No it uses all the other colours for photosynthesies so gives out the green that it doesent use.
Why is an indicator a valuable tool for measuring pH?
Most acidic solutions and basic solutions are colourless and transparent. Therefore, you cannot tell the difference between an acid and a base by appearance alone. One safe way to determine wether something is an acid or a base is to use an indicator.
What name is given to an indicator which gives different odor in different medium?
odour indicator
How is the index and table of contents different?
They are different because the index gives you a guide and the table of contents gives you the page numbers
What colours then mixed gives orange?
Red and yellow
What colours gives you pink?
add white to red

Why is the study of spectra so important?
It is used to see the colours that it gives off, if you know the colours you then know what atom it is.
What is the similarity in color?
well all are similar because there are the three primary colours which a combination of 2 or more of them gives us different colours in painting the three are blue yellow and red but in light perspective instead of blue its green weird or what
Can newton's rings exp done by mercury vapour lamp?
Mercury vapour gives out several colours of different wavelength the rings formed with different colours would get overlapped and so chaotic image will be there. Therefore, it will require that you use light filters, yellow, green and blue for the different spectral lines, then you get monochromatic light and not a chaotic image at all.
What is the difference between light color and pigment color?
Light is transmitted colour, it is called additive colour. Pigment is reflected colour. They have different primary colours. When the light is reflected from something, as in paint, the three primary colours are red, yellow, and blue but for transmitted light the primary colours are red, green, blue - RGB. Computer screens and televisions use RGB colour. Red + Green gives yellow; Red + Blue gives magenta and Green + Blue gives cyan.
What gives stars their colours?
Their temperature. Red is the coolest and blue is the hottest.
A compound that can reversibly change color depending on conditions such as pH?
They are comonly known as "indicators" as the color change is useful for indicating what the pH of a solution is.
In the estimation of sodium carbonate you use methyl orange as an indicator?
yes .. we use methyl orange as an indicator ... when added it gives a straw yellow colour
