I have about a lot of questions. and i did around 85% of the work. the other questions i had to leave blank because they were quite confusing and pretty hard for me. These are quite alot..answer what u may wish.. (If No One Wanna Help Thanks Anyways Just don't get mad at me) :)


1. a) Do tiny particles in the air scarrer high or low frequencies of light?

b) What frequencies do large particles scatter?

2. What is a spectroscope, and what is its funtion?

3. Does the red light from glowing neon gas have only one frequency or a mixture of frequencies?

4. Why might atomic spectra be considered the "fingerprints" of atoms?

5. What is the name of the color produced by a mixture of green and blue light?

6. What colors of spots are lit on a television tube to give full color?

7. What are complementary colors?

8. What color is the complement of blue?

9. What color would a yellow cloth appear if illuminated with sunlight? With yellow light? With Blue Light?

10. How could you use the spotlights at a play to make the yellow clothes of the performers suddenly change to black?

( Short Answers will be highly appreciated )


Thank you very much...
Thanks in return :)

I'm wondering why you consider these "quite confusing". Each asks for a specific piece of information. Nothing confusing about that. There is no problem to solve or reasoning to do. If you do not already know the information asked for, you look it up in your textbook.

its hard for me :frown:
 
Some of these answers will be in google.com!
If you textbook doesn't have them...
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
