Answer:
A mesmerizing Siberian mystic named <em><u>Grigori Rasputin</u></em> was brought in to help Alexei.
Explanation:
Prince Alexei Nikolaevich was the only son and heir apparent of Tsar Nicholas II, the emperor of the Russian Empire. Born after four sisters, his birth was met with such joy and relief not only to the Russian people but to his parents.
As fate would turn out, Alexei would become one of the sources for the downfall of the Roman empire. Shortly after his birth, it was discovered that he was suffering from the hereditary disease of hemophilia from his mother's side. After the physicians and doctors couldn't find any cure, a mystic and faith healer Grigori Rasputin was brought in to help the suffering child. Rasputin was a self-proclaimed saint who was believed to use hypnosis to help calm the child, leading to his parents having full faith in the ability of the saint in 'healing' their baby. Rasputin would later become an influential part of the Empress's life but would also be assassinated by the Tsar's own relatives.
It takes nd/ (lambda*f) time or a short pulse of light to travel from one end of the glass to the other.
If we talk about free space, that is, vacuum, light travels at a speed of 3x10^8 m/s, yet inside a glass light travels at a speed of v= c/n, where v is the velocity of the light and n is the refractive index. Now,
v=d/t,
so t= d/v
t= d/ (c/n)= n*d/c
c= lambda*f
t= nd/(lambda*f)
here, d is the thickness of the block, t is the time required and c refers to speed of light.
