Concept #1: Particle Nature of Light Intro

Example #1: Particle Nature of Light

Practice: Rank the following in terms of decreasing energy: Gamma energy, visible light 1 (ΔE = 4.39 x 10^{-19} J), microwave and visible light 2 (λ = 595 nm).

Which statement related to particle and wave properties of matter is correct?a. Particles exhibit diffraction while waves do not.b. A wave travels straight through a slit.c. Interference patterns are observed when a wave passes through a barrier with two slits.d. Particles interfere constructively and destructively whereas waves do not.

A photon has a wavelength of 759 nm. Calculate the energy of the photon in joules. Enter your answer in scientific notation.

A certain shade of blue has a frequency of 7.01 x1014 Hz. What is the energy of exactly one photon of this ight?

Be sure answer all parts.How many photons at 586 nm must be absorbed to melt 5.15 x 102 g of ice? (It takes 334 J to melt 1 g of ice at 0°C.) (Enter your answer in scientific notation.) On average, how many H2O molecules does one photon convert from ice to water? (Enter your answer in scientific notation.)
