Double check my answers to physics questions plz!!??

1)Why does a sunset appear red?
a) because blue light is scattered otu of hte sun's rays as they apss through th longer than- normal light path
b) air tends to absorb blue light more than red light
c) scattering in air progressively lowers the frequency of the light in its long air path
d) blue light is refracted out of hte beam in the long air path

2) The kind of siggnal that you would most lkely be able to receive on yoru antenna if you lived on the opposite sid eof a mountain from teh transmitting antenna would be..
A) AM radio
b) FM radio
c TV picture
d) microw. telephone transmission
BECAUSE
e. the TV signal is transmitting light
f. it has teh llongest wavelength and would therefore difract around teh mountain
g. it has the highest frequency and would therefore diffract around the mountain
h. FM signals can be detected better beause interference of waves removes teh amplitude modulation of waves

7. the velocity of a sond wave depends upon the
freq., amplitud, pitch, or medium?

i'm not sure about the first two, but i know the last one is frequency. think about the formula velocity=frequency times wavelength.

鈽?just a minute, I have to see your profile first;
no, I don鈥檛 like it;

spelling, spelling my boy! Ok, here you are!
