FINALS - SINGLE - SLIT

Question 1

When a wave such as light goes through a slit or an obstacle, it
bends around the corners or through a fissure. This property is called _____

Answer 1

DIFFRACTION

Question 2

refers to the bending of light as it goes through an edge or
aperture, thus forming a fuzzy edge.

Answer 2

Diffraction

Question 3

Happens at the boundary
between two media (e.g.,
air and water).

Answer 3

Refraction

Question 4

Caused by a change in
wave speed due to
different medium
properties.

Answer 4

Refraction

Question 5

Common in light, sound,
and seismic waves.

Answer 5

Refraction

Question 6

Most noticeable when the
obstacle/opening is about the
same size as the wavelength.

Answer 6

Diffraction

Question 7

Wave spreads out in a circular
or fan-like pattern after
passing the obstacle.

Answer 7

Diffraction

Question 8

Happens in all types of waves
(light, sound, water, etc.).

Answer 8

Diffraction

Question 9

Observe that a_____ rather than a sudden
one, in the intensity of light occurs as it changes from
dark to light.

Answer 9

slow increase,

Question 10

Diffraction fringes at the boundaries of the shadow are
created when the light is ________

Answer 10

monochromatic.

Question 11

_______ create more diffracted light.

Answer 11

Longer wavelengths

Question 12

______________________ (1629-
1695) demonstrated a very
practical method to identify
the manner and direction of
the propagation of waves.
