What is the acceleration of light from a star?
The speed of light is constant in a vacuum and is approximately 299,792 kilometers per second. Light from a star travels at this speed from the star to Earth without acceleration.
What unit of measurement is used for the radius?
Any measure of length, such as meters, centimeters, or light-years.
Can focal length and radius of curvature of a lens be same?
No, the focal length and radius of curvature of a lens cannot be the same. The radius of curvature is twice the focal length for a lens. This relationship is based on the geometry of the lens and the way light rays converge or diverge when passing through it.
Light from a star travels to earth in a straight line at a constant speed of almost 300000 km s what is the acceleration of light?
The speed of light is constant at about 300,000 km/s in a vacuum, so light does not experience acceleration.
What units is the radius of a circle measured in?
Any unit of length: millimeter, meter, kilometer, light-year, etc.
What is within 1 light year radius of earth?
Within a 1 light-year radius of Earth, there are numerous stars in the Milky Way galaxy, such as Proxima Centauri, Alpha Centauri A and B, Barnard's Star, and Sirius. However, there are no known planets in this immediate vicinity.
Why might using speed of light to determine the length of the meter be more reliable than using a measured distance around earth?
The speed of light in vacuum is a universal constant. The distance around the earth depends on the line of measurement. Because of its rotation, the earth is not a perfect sphere: its equatorial radius is 0.3% greater than its polar radius. Consequently the measurement is affected by the exact line along which the radius is measured. Furthermore, there are two kinds of variations in the equatorial radius. One is a long-term variation caused by the distribution of mass on the surface: possibly the ocean mass. There is also the short term variation caused by the gravitational pull of the moon.
How is the focal length of a spherical mirror affected when the wavelength of light used is increased?
The focal length of a spherical mirror is not affected by the wavelength of light used. It is determined by the mirror's radius of curvature and refractive index of the surrounding medium. The wavelength of light only influences the diffraction effects, not the focal length.
What is the schwarzschild radius of earth?
The schwarzschild radius of the Earth is about 8.7 x 10 to the negative 3m. The schwarzschild radius is the radis of a sphere that is around a non-rotating blackhole. You find the Rs, or radis, by multiplying the gravitational constant(G), the mass(M), and two. You divide this by the speed of light(c) squared.
How do you calculate the average radius of earth's orbit lif it takes 500seconds for light to reach earth from the sun?
The average radius of Earth's orbit can be found using the formula: distance = speed x time. We know that the speed of light is approximately 299,792 km/s. Therefore, the calculation would be: average radius = (299,792 km/s) x (500 seconds) = 149,896,000 km.
Formula for the radius of the curvature of the concave lens?
radius of curvature is double of focal length. therefore, the formula is: 1/f = (n-1)[ 1/R1 - 1/R2 + (n-1)d/nR1R2] here f= focal length n=refractive index R1=radius of curvature of first surface R2=radius of curvature of 2nd surface d=thickness of the lens using this, if you know rest all except one, then you can calculate that.
How far from the earth is Wezen?
1,800 light years away. it is hotter than our sun (6200 Kelvin) and the radius 195 times that of the Sun, which makes the star almost as big as the Earth's orbit.
