into two separate beams. The splitting of the beam is accomplished either statically using a partially transmitting mirror or through attenuation of the beams optical devices. The diffraction grating and the slit You are probably familiar with the way that a prism splits light into its component colours. A diffraction grating does the same job‚ but more efficiently. The blue arrows show the way the various wavelengths of the light are sent

inaccurate which also led to the model being inaccurate. After Watson and Crick’s request to collaborate with Rosalind was denied they were also told to cease all work on DNA (Biography‚ 2016). On May 2‚ 1952 Raymond Gosling took photo 51‚ an X-Ray diffraction photo that would quickly become well known. This only added to the proof that DNA’s structure was that of a helix‚ Rosalind didn’t let it go that easy though‚ photo’s of ‘A’ DNA were less clear and she wanted to find out why (Biography‚ 2016).

Franklin¡¯s 26th birthday. Further‚ Franklin had given up her fellowship to become a physical chemist at the British Coal Utilization Research Association at age 22. She was indeed an efficient and driven researcher. Franklin utilized the X-ray diffraction techniques (that she has become most famous for) while working in a Paris laboratory between 1947 and 1950‚ with crystallographer Jacques Mering. 	X-ray crystallography helped determined the three dimensional structure of DNA when Franklin

The Hubble Space Telescope is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. A aperture telescope in low Earth orbit‚ Hubble’s four main instruments observe in the near ultraviolet‚ visible‚ and near infrared. The telescope is named after the astronomer Edwin Hubble. Hubble’s orbit outside the distortion of Earth’s atmosphere allows it to take extremely high-resolution images with almost no background light. Hubble’s Deep Field has recorded some

 Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The unknown element color will be a orange-red color. “Every element

also studying DNA. The Cambridge team ’s approach was to make physical models to narrow down the possibilities and eventually create an accurate picture of the molecule. The london team took an experimental approach‚ looking particularly at x-ray diffraction images of DNA. In 1951‚ Watson attended a lecture by Franklin. She had found that DNA can exist in two forms‚ depending on the relative humidity in the surrounding air which helped her deduce that the phosphate part of the molecule was on the outside
