Nature of light

QuestionAnswer
Which theory, waves or particle of light, is the one that scientists currently believe is correct? wave - particle duality.
What is the value of the Planck's constant? 6.63 x 10^-34
What is the equation for the energy of the photons? E = hf
What is the equation for the radiation flux? F = P / A
What is the name give to the particles of light? Photons
What is the equation for the speed of wave? speed = wavelength / time
Points that are a whole wavelength apart oscillate . . . in phase
Points that are wavelength / 2 apart oscillate in . . . antiphase
What is the principle of superposition? Where two or more waves meet, the total displacement at any point is the sum of the displacements that each individual wave would cause at that point.
What is the lowest frequency at which resonance occurs? Fundamental Frequency OR First Harmonic
What is a standing wave? Intereference between two waves travelling in opposite directions.
When does resonance occur? When the frequency of vibration of the cord is increased.
The angle of incidence is equal to . . . The angle of reflection

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
