At night, a street light appears bigger and brighter than other street lights on the same street, just like some stars in the sky.
A student lives on a street that is long and straight. While walking home at night, the student observes three street lights at different distances. Data about each light are shown in Table 1.
Which statement describes how the brightness of light relates to distance?
The less bright the street light appears, the closer the student is to it.
The brighter the street light appears, the closer the student is to it.
The less bright the star appears, the closer it is to Earth.
The brighter the star appears, the farther it is from Earth.
If the student moves away from Arcturus, the brightness of this star would appear to _____
increase
stay the same
decrease
Which claim is accurate?
The Sun appears smaller and brighter than other stars because it is the closest star to Earth.
The Sun appears larger and brighter than any other star because it is the closest star to Earth.
The Sun appears larger and less bright than other stars because it is the farthest star from Earth.
The Sun appears smaller and less bright than any other star because it is the farthest star from Earth.
