The telegraph reached San Francisco in 1860, completing a crucial link in the transcontinental telegraph system. Once established, it quickly expanded throughout the city and surrounding areas, gaining widespread use within a few years. By the mid-1860s, the telegraph was well-integrated into communication networks, transforming how information was shared in the region. Overall, the expansion took just a few years, reflecting the rapid technological adoption of the time.
as soon as the telegraph operator completes the message it is received at the other end.
In 1838 Samuel Morse perfected Joseph Henry's invention of the electromagnet. It was not until 1843 that the government funded a telegraph graph line from Washington to Baltimore.
Before the Telephone became available for use long distance electronic communication consisted of The telegraph. To take advantage of this form of communication one had to take ones message to a telegraph office where a telegraph operator would send it using Morse code to a recipients post office where it would be deciphered and sent on as a telegram to the recipient While the Telegraph was a great step forward in communication it was certainly far more cumbersome and difficult to take advantage of then modern telephony. http://www.sendatelegram.com/telegrams_history.asp
Samuel Morse invented the telegraph and also the Morse code.
In the mid-19th century, it would have taken approximately 10 minutes for a telegraph signal to travel from the east coast to the west coast of the United States. The signal would need to be relayed through a series of telegraph stations across the country.
Before the telegraph people sent written letters and could take from days to weeks possibly a month to receive it.
The difference is it take wire less reciver
You wrote your message on a telegraph form.You handed the telegraph form to the clerk at your local telegraph office.The clerk would count the words of the message and tell you how much it would cost.You would pay the clerk.The clerk would put your telegraph form in the stack of outgoing telegrams.The telegraph operator at your local telegraph office would send the telegrams on the telegraph forms in the stack of outgoing telegrams using the telegraph key.The telegraph operator at the recipient's local telegraph office would listen to the telegraph sounder and write the telegrams down on telegraph forms and put them in the stack of incoming telegrams.Telegraph delivery boys/men would take the telegraph forms in the stack of incoming telegrams and go around town delivering them to the recipients.

The development of the telegraph spanned several decades, with significant contributions from various inventors. Samuel Morse and Alfred Vail developed the first practical electric telegraph and Morse code in the early 1830s, with their system being successfully demonstrated in 1844. However, advancements continued throughout the mid-19th century, making the telegraph a more reliable and widespread communication tool. Overall, the process involved multiple innovations and refinements over a period of around 10 to 20 years.
The telegraph was much faster than horseback messaging, as it could send messages instantly over long distances at the speed of electricity. This was a significant improvement over the time it took for messages to be delivered by horseback, which could take days or even weeks depending on the distance.
You may need to rephrase the question. Thermal expansion is the amount a material expands or contracts under temperature change; expansion is instantaeous with temperature. When temperature is reached, so is expansion. It may take time to rach temperature, however.
