Ans :
Energy of the light is directly proportional to its frequency.
It is given as :
E = h x f
where E is energy , h is planck's constant and f is frequency
The frequency of blue light is more than the orange light , so it carries more energy than the orange.
which light carries more energy: orange light or blue light? explain
Which of the following visible colors of light has the highest frequency? blue orange O red yellow green
12.(a) What is the percentage difference between the speeds of orange light and blue light in polystyrene, based on Table 25.2 in the textbook? (b) What is this percentage difference in diamond?
How much energy does a photon of blue light with a wavelength of 465 nm have? How much energy does a photon of red light with a wavelength of 663 nm have? Photons of which color of light (red or blue) have greater energy? red or blue
A metal foil has a threshold frequency of 5.45 x 1014 Hz. Which of the colors of visible light have enough energy to eject electrons from this metal? indigo yellow blue green violet orange red
Place the following types of radiation in order of the properties described. orange light, microwaves, gamma, green light, ultraviolet, blue light a. Increasing wavelength- b. Increasing energy- c. Decreasing frequency-

1. What colors would be reflected by an orange tab if you placed it in red, green, or blue light? Justify your response with the results you had for red and yellow tabs in red, green, and blue 2.If you have a yellow light source and every color filter to use, could you produce every other possible color? Explain. 3. If an object is 20 cm from a lens and the image is formed 10 cm behind the lens, what...
based on chromatographic methods lab which dye ( methylene blue and methylene orange) is more polor ? how did you distinguish between chlorophyll a nad chlorophyll b in your TLC analysis ? which structural feature of the molecule accounts for this observation ? compare and contrst your TLC results whe n100% acetone was used vs when 100% hexane was used what do your result suggest the polarities of the dyes in spinach ?
