It have a shorter focal length because there is more time for the light rays to come together

Do thick convex lenses have longer or shorter focal lengths than thin convex lenses?
As a thicker lens has more material to do bend the light further it it would have a shorter focal length
What cause lenses to have different focal lengths?
Lenses have different focal lengths due to their varying shapes and materials. A thicker lens will have a shorter focal length, while a thinner lens will have a longer focal length. Additionally, the refractive index of the lens material will affect its focal length.
What factor determines the focal length of a lens?
The curvature of the lens surfaces and the refractive index of the material the lens is made of determine the focal length of a lens. Thicker lenses with more curved surfaces have shorter focal lengths, while thinner lenses with less curved surfaces have longer focal lengths.
Does waves with longer wave lengths have a higher frequency that waves with shorter wave lenghts?
No, waves with longer wavelengths have lower frequencies and waves with shorter wavelengths have higher frequencies. Frequency is inversely proportional to wavelength in a wave.
Why pencils are designed to have longer lengths than pens?
Pencils are designed with longer lengths to accommodate the eraser at the end and to provide a comfortable grip for writing or drawing. Pens, on the other hand, have a shorter length because they have a built-in ink cartridge that needs to fit within the pen casing.

Is the radius shorter than a chord?
Chords come in various lengths, which may be longer, shorter, or the same length as the radius.
What is the difference between shorter and longer focal lengths?

What is a graduation hair cut?
A graduation haircut uses hair lengths to create weight in the hairstyle. It is not uniform layering, but a mix of shorter and longer lengths.
How do you find the side lengths of a 20-70-90 triangle?
There are an infinite number of different sets of lengths that will do it. You have to start by choosing the length of one side, and when you do that, here's how to find the others: Shorter leg = (longer leg) x 0.364 Shorter leg = (hypotenuse) x 0.342 Longer leg = (shorter leg) x 2.747 Longer leg = (hypotenuse) x 0.94 Hypotenuse = (shorter leg) / 0.342 Hypotenuse = (longer leg) / 0.94
Does waves with longer wave lengths have a higher frequency that waves with shorter wave lenghts?
No, waves with longer wavelengths have lower frequencies and waves with shorter wavelengths have higher frequencies. Frequency is inversely proportional to wavelength in a wave.
What set of lengths can be used to make a triangle?
There are many lengths that can be used to make triangles. Basically take the longest side, add the two shorter sides together, it can be a triangle as long as the 2 shorter sides added together are longer than the longest side.
How can you tell if a painted turtle is a boy or girl by its shell?
The male turtles have a longer tails and females has a shorter tails.
What type of lenses are used when photographing people's faces from a distance?
You would ask for a telephoto lens in a shop. Scientifically they are convex lenses with longer focal lengths than a normal lens. A normal lens has a focal length between 21 and 35 mm, whereas the medium telephoto lenses used for portraiture have focal lengths between 70 and 135 mm.
What is true about the lengths of the three sides of a triangle?
For a triangle to exist, the sum of the shorter two sides must be longer than the third side.
