Speed of light and Energy of electromagnetic radiation?
If something has more energy, shouldn't it go faster? So does gamma rays go faster than visible light? I thought visible light's speed is the barrier beyond which nothing can go faster. So how is it that gamma rays, having more energy than visible light, has the same speed as visible light?
6 AnswersPhysics1 decade agoHow do I correct a photograph with bad exposure?
I took a picture of a dark brown signpost. It's one of those new touristy signposts. Behind it is a field. The sky was partially overcast.
The sky was overexposed and the signpost is very dark. I tried gamma correction but the whole picture becomes either too bright or too dark. I tried to reduce the contract, which helps bring out details in the clouds, but the picture has a greyish tint. Changing brightness levels does the same.
Is there any way I can improve the picture? I am using freeware image manipulation software (IrfanView and Serif PhotoPlus 6).
Thanks.
3 AnswersPhotography1 decade agoVisiting Big Sky Country?
An old friend invited me to visit Montana. I'm open to visiting SD and WY too. I have visited Yellowstone once, on a whirlwind tour thru the park. I'm thinking of seeing Mt Rushmore and maybe Devil's Tower, and maybe Galcier National Park and maybe the Grand Tetons.
I am in love with the IDEA of big skies but don't know what to expect.
I'd like to hear from you folks what to see/do in (i) MT (ii) SD/WY. Thanks.
PS - Lol, Yahoo Answers doesn't even have a category for MT. Is this a warning for what to expect there? :-)

I am thinking of getting a 3G WCDMA cellphone, but would like to know if it can operate in areas using CDMA? For example, a Nokia 3G phone operating in the US? Thanks for assistance.
