Dark phase does not require light. Even thougg it does not take place at night. Why?
Homework Answers
Dark phase is the subsequent phase that follows the light phase (oight reaction ). Fir light reaction light is essential. Light phase stops when the availability of light decreases. Hence dark phase also stops.

Which of the following best explains why the Calvin Cycle can take place during the day? O a. the Calvin cycle relies on the products of the light reactions, not the presence or absence of light itself. D.the Calvin cycle does not directly require dark to function. O c. the Calvin cycle is not directly connected to the light reactions or the presence or absence of light. O d.the Calvin cycle is part of the electron transport chain...

A recent study? examines the effect of light at night on body mass gain in mice. Eighteen mice were randomly assigned to one of two groups: the Dark group had a normal light/dark cycle with darkness at night and the Light group had a dim light on at night, equivalent to having a television set on...

results?
EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a...

Chapter 8, Section 1, Exercise 033 LIGHT AT NIGHT MAKES FAT MICE Studies have shown that exposure to light at night is harmful to human health. A study in mice shows that light at night has an effect on weight gain after just three weeks. In the study, mice were randomly assigned to live in one of three light conditions: LD had a standard light/dark cycle, LL had bright light all the time, and DM had dim light when there...

Can somebody rephrase this into simple words?
It is about dark and bright fringe formula.
What does no phase mean? What does phase change mean regarding
to light beam?
We can understand the origin of the dark fringe at the point of contact by recalling that ray 1 undergoes no phase change on reflection, whereas ray 2 experiences a 180° phase change due to reflection. It follows, then, that when the path difference, 2d, approaches zero, rays 1 and 2...
