Which of these best describes the type of lens shown in the ray diagram?
(1 point)
It shows a convex lens. For this type of lens, the image position depends on the object's position relative to the focus point.
It shows a convex lens. For this type of lens, the image is always on the opposite side of the lens as the original object.
It shows a convex lens. For this type of lens, the image is always on the opposite side of the lens as the original object.
What happens to sound waves from an object as it moves toward you? (1 point)
The pitch gets lower because of an increase in wavelength.
The pitch gets higher because of an increase in wavelength.
The pitch gets higher because of an increase in frequency.
The pitch gets lower because of an increase in frequency.
The pitch gets higher because of an increase in frequency.
The correct answer is:
It shows a convex lens. For this type of lens, the image is always on the opposite side of the lens as the original object.
To determine the type of lens shown in a ray diagram, we need to examine the behavior of the rays as they pass through the lens.
In the given options, both choices refer to a convex lens, which is a lens that bulges outward. However, we can further examine the statements to determine the correct answer.
The first statement correctly states that for a convex lens, the image position depends on the object's position relative to the focus point. This is an accurate statement and aligns with the behavior of a convex lens.
The second statement correctly states that for a convex lens, the image is always on the opposite side of the lens as the original object. This is also a true statement, as convex lenses converge light rays and form real images which are projected onto a screen or surface.
However, in terms of describing the type of lens shown in the ray diagram, the first statement provides a more specific and complete explanation. It not only mentions the behavior of the image position relative to the focus point, but it also correctly identifies the lens as convex.
Therefore, the best description of the lens shown in the ray diagram is:
"It shows a convex lens. For this type of lens, the image position depends on the object's position relative to the focus point."
