What is the wavelength of light in water (=1.33 ) if its wavelength in air is 5.30×10 %&˛'? Answer – the change in optical densities of the mediums is equal to the change in wavelength that will occur.
Formulas and Constants: f = c/λ E = hf. f = frequency. c = speed of light (3.0 x 108 m/s) λ = wavelength. E = energy h = Planck’s constant (6.6262 x 10-34 J•s) 1. Calculate the λ given the frequency of radiation is 5.10 x 1014 hz. 2. Calculate the frequency of red light with λ = 6.50 x 10-7m.
1. To make a wavelength of rope shorter, one should shake the rope at a __higher______ (higher or lower) frequency. 2. The primary difference between an electromagnetic wave and a mechanical wave is that a(n) _electromagnetic__ wave can travel through empty space, while the other cannot. 3.
STUDENT WORKSHEET. OBJECTIVES. 1. Use diffraction grating and diffraction angle to calculate wavelengths of light. 2. Recognise differing wavelengths in the light spectrum to predict. calculations. Retort stand. Dowel with screen.
More Practice: Energy, Frequency, Wavelength and the Photoelectric Effect. There are two equations you should know: E = h! and c =!!" !=!!!!!∴!!!=!!! E = energy (J) = wavelength (m) ! = frequency (Hz or s-1) h = Planck’s constant, 6.626x10-34 J∙s c = the speed of light in a vacuum, 3.00 × 108 m∙s-1
Speed /Frequency / Wavelength Equation: Speed of all Electromagnetic Spectrum Waves (c) = 3.0 x 108 m/s c (m/s) = ν x λ ν (Hz) = c ÷ λ λ (m) = c ÷ ν 1. Violet light has a wavelength of 4.10 x 10-12 m. What is the frequency? 7.31 × 1019 Hz 2. Green light has a frequency of 6.01 x 1014 Hz. What is the wavelength? 4.99 × 10-7 m 3.
wavelength and violet light has the shortest wavelength. When white light shines towards a glass prism, it splits up into the different coloured wavelengths. Each wavelength slows down and changes direction. Red light changes direction least, and violet light changes direction most. The light leaving the prism is spread out into its different ...
