A circular tablet with a radius of 20 cm and a uniform luminosity of 10.5 cd / m ^ 2 illuminates a small flat surface with an area of 1 cm ^ 2 and at a distance of 1 m from the center of the tablet. The orientation of this small surface is such that its perpendicular to the line joining the centers of the two surfaces forms an angle of 45 °. This line is perpendicular to the circular disk. Determine the luminous flux on a small surface

The lightbulb and the lamp illuminate a sheet of paper equally. The 1750 lm lamp is 1.25 m away from the sheet of paper, while the lightbulb is 1.08 m away. What is the lightbulb’s luminous flux?arrow_forward( Why? From fireworks to stars, the color of light is useful in finding out what's in matter. The emission of g by hydrogen and other atoms has played a key role in understanding the electronic structure of atoms. Trace materials, such as evidence from a crime scene, lead in paint or mercury in drinking water, can be identified by heating or burning the materials and examining the color(s) of light given off in the form of bright-line spectra.

Which of the following statements is a correct interpretation of these spectra? Intensity 1 2 Wavelength object 1 is brighter than object 2 at all wavelengths O object 1 is blueshifted so it is moving toward us O object 1 is closer to us than object 2 O object 1 is redshifted so it is moving away from us O object 1 is blueshifted so it is moving away from usarrow_forwardwhy is ultraviolet light (320 nm) more penetrating than a red light (700nm)arrow_forward
- Go outside on a clear night, wait 15 minutes for your eyes to adjust to the dark, and look carefully at the brightest stars. Some should look slightly red and others slightly blue. The primary factor that determines the color of a star is its temperature. Which is hotter: a blue star or a red one? Explainarrow_forwardAn idealized radiating object does not reflect or scatter any radiation but instead absorbs all of the electromagnetic energy that falls on it. Can you explain why astronomers call such an object a blackbody? Keep in mind that even stars, which shine brightly in a variety of colors, are considered blackbodies.
