actually the frequency donot change but apparent change in frequency is observed by the observer...........(may be this help u)
0.5 m in 2 hours would be 1 m per hour.
no , it cannot be observed in same conditions of incident light because, the threshold energy will be different for different metals.so in that particular threshold energy only the photoelectric effect for that metal can be observed.....
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.
There are many different physical properties of matter that can be observed. Consistency, color, and texture are just 3 properties.
Parallax is the apparent movement of an object across a background when observed from two different places.
A planet is said to be in retrograde motion when its apparent motion - the motion as seen by us, against the background stars - is from east to west.Planets spend more time in prograde motion, from west to east. The apparent movement of Sun and Moon against the background stars is also from west to east. Not to be confused with the daily motion, due to Earth's rotation.

It is usually calculated through the parallax. The apparent position of the star, against the background of stars much further away, is observed at two opposite points in the earth's orbit around the sun. The apparent angular shift is recorded. Then, knowing the distance between the two positions of the earth, and a bit of trigonometry, the distance to the star can be calculated. An apparent displacement of 1/3600 degree (or 1 second) is called a parsec, and is equal to 3.086*10^13 kilometres
Apparent solubility represents the solubility one observed during the experiment while the intrinsic solubility meant to the real or true solubility.
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.

He observed the same movement. When the experiment was repeated with rock dust the same movement was observed.
yes, Arno Penziaz and Robert Wilson picked up the first signals
