Question

Which of the following is/are correct regarding candle clock?
A) Candle clock used tall candles to show the passing of time.
B) The candles had evenly spaced lines on them that were usually marked with numbers for each hour.
C) When the candle burned down to one of the numbers, it showed what time it was.
D) All of the above

Answer 1

Hint: A candle clock was used to calculate or measure the time in past times and is no longer in use in the present times. On candles, some marks were made to specify the time. Candle clock was able to easily tell time whether indoors, at night or during the rainy days.

Complete answer:
In the past, a candle clock was utilized to measure time. They used tall candles to show the passing of time. There are blemishes on the flame. As the flame burns to the ground and the imprints vanish, you can quantify the time that has passed. The imprints on a flame are set to quantify the death of the hours. At the point when a light has consumed the wax between two denotes an hour has passed. The flame needs to consume consistently. In the event that it is in a draft it will consume all the more rapidly so it is set in a holder which lets you see the imprints on the light yet shields the flame from drafts.

The dispersing of the imprints on the candle is worked out in the accompanying manner. Two candles are set up close to another gadget which estimates time. The candles had evenly spaced lines on them that were usually marked with numbers for each hour for estimation of time passed. Today it would be a mechanical check yet in the past it might have been a sundial or a sand clock. One of the candles is lit and when an hour has passed the tallness of the flame is contrasted and the dim light and an imprint is made on the side of the dark flame.

After one more hour has passed a subsequent examination is made and a subsequent imprint is made in the dim light. This technique is rehashed each hour until the principal flame wears out. At the point when this happens the subsequent flame has a progression of imprints along its side which measure the death of the hours.

On the basis of the above data about candle clock, we conclude that all the given options A, B, C are true.

Hence, Option D is correct.

Note: Candle clocks were used in ancient times. Since then, a variety of methods and instruments have come into play for time estimation. With each method different from the others, in one way or the other, we have come a long way to the mechanical wall clocks that we use nowadays in our homes. A brief knowledge about these methods and instruments for time estimation will be beneficial.
