What is the wavelength in meters observed with a frequency of (4.5x10^15)?
Answer with 2 significant figures and it must be in scientific notation.
Note: Your answer is assumed to be reduced to the highest power possible.
Your Answer:
Answer
x10
units
Our Sun has a surface temperature of about 5800 K. Find the emitted power per square meter of peak intensity for a similar star with 4600 K that emits thermal radiation. Express your answer in scientific notation and with three significant figures.
The intensity of light from a central source varies inversely as the square of the distance. If you lived on a planet only half as far from the Sun as our Earth, how would Sun’s light intensity compare with that on Earth? How about a planet 10 times farther away than Earth?
