By using the specific heat capacity theory.. C=J/m x change of temp By doing that experiment I have the data if specific heat capacity of water, and the mass of water before I started the experiment. The change of temperature will be determined by the data logger during the experiment. Can I...

Hey guys, it is possible that to observe the energy outcome of visible light? By adding colored frame in front of the light source and shined on a beaker with water Using data logger to record the data, how long should I take the experiment? Thanks for helping

Thanks so much for helping

Hey guys Today I've done an experiment and I found that when different color of light from the same light source (put of different color filter on the same light source) shine on a beaker of water, the temperature of the water will rise. And different light will rise the temp of water in...

so, apart from doing experiment with the frequency topic, what topic will you guys advice me to do? My assessment is to develop an experiment to prove a physics theory, but the main thing is the experimental way must be designed and not used before. Thanks for all your advices! really! thanks...

it seems interesting experiment, can you talk a little bit more about your student experiment?

Well i am not making the sound by rubbing your finger rather than hitting the glass, i am actually going to use some object to hit on the glass. But, to me, the hardest thing is to know the theory behind this vibration and how can i record these data.. I am really interested in this topic...

Okay. Is that mean the vibration of the glass cause the vibration of the air. All the sound that I heard was the sound of the vibrating air? I am still very confusing now:( thanks for that

Yes I know they all vibrating once the chopstic hit the beaker. But is the vibration theories will be much more likely to apply in this case? Or it's really related to the Colum's Law?

So the topic seems confused me right now Does it mean that the frequency of the sound waves which produced from their around, the glass and the water will decrease when the volume of the water in the beaker increase? Is my concept right? Is there anything to do with the distance between the...

Thanks for that =] Problems solved!

So can i use the laws of waves to prove that the distance between the water surface and the end of the beaker did affect the sound provided. Then use some data loggers to prove that the frequency did increase once the water surface closer to the end of the beaker? As i am using the same shape...

All of these help so much. I am so interested in this topic now. So please correct me if I am wrong. The idea that I got was the frequency of the sound is proportional to the volume of the water in the beaker. And once the water surface closer to the top of the beaker the higher frequency we...

So there isn't any physics theory shows that the volume of the water in those glasses have a clear relationship with the sound produced? If there is, i would like to have a look of that Physics Law Well actually i am a having a physics assessment which i can choose whatever topic i want. So if...

This question just pop out from my mind when my brother played with the glass cups with different volume of water in it to produce some kind of music When I tried to do some research on net I found not much informations So just want to know that are there any theories that proved the volume...
