Sir Edward Appleton: Pioneer in Atmospheric Physics and Nobel Laureate

Sir Edward Appleton, born in Bradford, England, significantly contributed to atmospheric physics and radar technology. A graduate of Cambridge University, he was awarded the Nobel Prize for Physics for his groundbreaking work on atmospheric layers using radio waves. His experiments led to the discovery of critical layers in the upper atmosphere and the development of frequency-modulation radar. Knighted in 1941, Appleton received numerous accolades, including the Medal of Merit from the U.S. and honors from France and Norway for his war contributions.

  2. Born in Bradford, England. • Joined the west riding Regiment. • He was awarded the Nobel Prize for Physics.

  3. It led him to the development of radar. • Graduated from Cambridge University. • He returned to Cambridge to research on atmospheric physics mainly using radio waves.

  4. He research the strength of the radio signals received at Cambridge. • Appleton discovered another layer 250-350 km high. • He was secretary of the department of scientific and industrial research.

  5. Appleton began a series of experiments. • proved the existence of layers in upper atmosphere.

  6. The position of the reflecting layer was identified. • And its height (60 miles above ground.)

  7. The method used was what is now called "frequency-modulation radar". • Appleton was knighted in 1941 being created K.C.B.

  8. a member of the Scientific Advisory Committee of the War Cabinet. • Awarded the highest civilian decoration of the United States - the Medal of Merit
