Why Sundials can't be used at night?
Sundials require sunlight.
Do sundials work in night time?
No, sundials do not work at night because they rely on sunlight to cast a shadow from a gnomon (the part that sticks up). Without sunlight, there is no shadow to indicate the time. At night, other methods, such as clocks or moon phases, are used to tell time.
What are the different types of sundials?
The main types of sundials are horizontal, vertical, equatorial, and polar. Horizontal sundials are the most common and have a flat plate with hour markings. Vertical sundials have a vertical dial face and are often found on walls or pillars. Equatorial sundials have a dial plate that is parallel to the equator, while polar sundials are aligned with the Earth's axis.
What are the problems with using sundials?
Some of the problems with using sundials include their reliance on sunlight, which makes them ineffective at night or on overcast days. They also require regular adjustment due to changes in the position of the sun throughout the year. Additionally, their precision can be affected by factors such as location, terrain, and the accuracy of the sundial's design.
Are there different types of sundials?
Sundials use the posidtion of the sun to cast a shadow on the dial. You can then read the number on where the shadow falls to get the time. As a result, no, there shouldn't be different types of sundials.
How does sundials work with ratio?
Sundials work with a ratio by calculating the amount of shadow cast on the ground in relation to the sun's position. These were largely used prior to the advent of the clock.
What is the biggest problem with sundials?
They don't work on cloudy days or at night
What are the types of sundials?
The two types of sundials are altitude and azimuth sundials.
What are sundials made out of?
Rock. Stone. Metal. It's the DESIGN that makes them work!
Why Sundials can't be used at night?
Sundials require sunlight.
When did they use sundials?
There is no specific date stated as to when sundials were first used.
Why do sundials need to be adjusted?
we have to adjust sundials to see the shadow and time
Do sundials work in night time?

Who made the sundials?
Sundials are normally made of metal, however the materials may vary. Sundials were thought to be used in around 3500 BC.
How sundials work?
As the earth rotates the sun moves across the sky from east to west. A sundial is set with the marker faceing north; as the sun moves across the sky the shadow of the marker wil point at the approiate hour. (sundials do not work before sunrise or after sun set)
Why were sundials used?
Sundials were used to tell time, back without watches.
