A "high-dry" lens is a "high power, non-oil immersion" lens. As focal depth decreases with magnification, a high power lens would have a much shorter working distance than 1cm. The student is looking at dust floating in the air, not the slide. Crank it down to 1-2mm, refocus and look again.

Is better for astronomers to measure parallax every year in the same spot?
Yes, measuring parallax from the same spot every year helps astronomers accurately calculate the distance to stars by observing their apparent shift in position. By observing the parallax over time, astronomers can account for the Earth's orbit and improve distance calculations.

How did Eratosthenes learn about the position of the sun?
Eratosthenes learned about the position of the sun by observing the angle of a shadow cast by a vertical stick in Alexandria at the same time a stick in Syene had no shadow. By measuring this angle and knowing the distance between the two cities, he was able to calculate the Earth's circumference.
Why would astronomers measure the parallax angle of a planet or star?
Astronomers measure the parallax angle of a planet or star to determine its distance from Earth. By observing the apparent shift in position of the object against the background stars as the Earth orbits the Sun, astronomers can calculate the angle and use it to estimate the object's distance.
What information can you get in observing the star?
In observing a star, you can determine its brightness, color, position in the sky, and any variations in brightness over time. You can also analyze the star's spectrum to learn about its chemical composition, temperature, age, and evolutionary stage. By studying the motion of the star, you can infer its distance from Earth and its relative motion in space.
What is his position at 1 second if distance 2 is -1 and distance 1 is -4?
Distance 1 is -4 so the position is -4!
What is the most accurate method for determining the distance to a nearby galaxy?
The most accurate method for determining the distance to a nearby galaxy is through the use of parallax measurements, which involve observing the slight shift in position of the galaxy against background stars as the Earth orbits the Sun. This method allows for precise calculations of the galaxy's distance based on trigonometry.
How is the distance to a star determined using the measure of parallax?
The distance to a star can be determined using the measure of parallax by observing the star from two different points in Earth's orbit around the Sun. By measuring the apparent shift in the star's position against more distant background stars, astronomers can calculate the star's distance based on the angle of the parallax.
How do astronomers use parallax to describe how we measure the distance to other stars?
Astronomers use parallax to measure the distance to other stars by observing how a star appears to shift its position against the background of more distant stars as the Earth orbits the Sun. By measuring this apparent shift, astronomers can calculate the distance to the star based on the angle of the shift and the known distance between the Earth and the Sun.
How do you know when an object has moved?
An object has moved when its position relative to a reference point has changed. This change can be detected by observing a shift in the object's location over time, using methods such as tracking its displacement or measuring its distance from a fixed point.
What do you meant by parallax method?
The parallax method is a technique used in astronomy to measure the distances to nearby stars. It involves observing how a star's position in the sky shifts relative to more distant background stars as the Earth orbits the Sun. By measuring this apparent change in position, astronomers can calculate the distance to the star.
