1. Calcuate the distance(km) from the Earth to the Moon if it takes light 1.3 seconds to make the trip?
2. Saturn is about 1.2 billionkm from Earth. How long does it take light to travel that distance?
(I was only given the wave equation, Max Plancks equation, De Broglies equation, Wilhelm Wiens law equation, and einsteins photoeletric effect equation but none of them have to do with time and distance so I'm not sure how to solve these.)
c = velocity of light = 3*10^8 m/s approx
d = c t = 3*10^8 * 1.3 = 3.9 * 10^8 meters
= 3.9 * 10^5 km
I guess you can do the second one now :)
To calculate the distance between the Earth and the Moon in question 1, you can use the fact that light travels at a speed of approximately 299,792 kilometers per second.
1. Since we know that it takes light 1.3 seconds to travel the distance, we can multiply this time by the speed of light to find the distance:
Distance = Speed × Time
Distance = 299,792 km/s × 1.3 s
Calculating this, the distance between the Earth and the Moon is approximately 389,729.6 kilometers.
Moving on to question 2, we can use the same principle to determine the time it takes light to travel from Earth to Saturn.
2. We are given that Saturn is about 1.2 billion kilometers away from Earth. Again, we can use the formula:
Time = Distance / Speed
Time = 1.2 billion km / 299,792 km/s
Dividing these values, we find that it takes approximately 4005.4 seconds for light to travel from Earth to Saturn.
Note: The equations mentioned (wave equation, Max Planck's equation, De Broglie's equation, Wilhelm Wien's law equation, and Einstein's photoelectric effect equation) are related to different areas of physics and are not directly applicable to calculating distances and times in this context.
