True
False
The _______ is a measurement of how long a wave is (Point B to Point F)
Compression
Wavelength
Amplitude
Reflection
The amplitude of a wave is measured by measuring
The distance between the middle line and the peak OR trough point
The distance between the peak and the trough point
The distance between two random points
The wavelength and the peak
Which type of waves are used in broadcasting?
X-rays
Infrared rays
Radio Waves
Gamma Rays
This T-shirt absorbs or reflects al of the colors of the rainbow?
Absorbs
Reflects
Why does the straw appear to be bent?
Light is reflected
Light is refracted
Light is turned
Light is absorbed
The wavelength of a sound wave is measured from peak to peak or trough to trough
True
False
Which Electromagnetic waves help doctors detect a broken bone inside your body?
UV light
Gamma ray
X ray
A leaf is green because
All colors are reflected except green
The light is not part of the EM
All colors are absorbed except green
The sun light shining on the leaf is green

Color Line
Frequency is defined as
the number of waves that pass over a specific time
the number of waves that pass through a prism
the number of waves of a soundwave
the distance between the middle line to the peak point of a wave
Light bends when is
refracted
reflected

refraction
Which of these best describes how light travels through an empty space
It travels straight but may change direction to avoid objects.
It travels in a straight line without stopping.
It comes to a stop after it travels a certain distance.
It changes direction often even if there are no objects.
Communication in space occurs by using radio waves because
space does not have waves
space is too big for sound to travel and light reflects more easily
sound needs a medium (like air) to be carried and space has not medium (it's a vacuum)
Higher amplitude of a sound wave equals higher intensity. More intensity means
greater pitch but wrong vocal notes
louder sound and more energy released
quieter sound and more energy released
nothing because energy does not change
Our eyes detect different energies of light (wavelengths) as
different polarities
different intensities
different colors
different spectrum
Sun carries energy to plants in the form of _______which is then converted into food by the producers
light
sound
calories
gamma ray
Microwaves rely on the following wave frequency:
microwave
gamma ray
visible light
x-ray
Sunlight is special because
contains white OR black light
contains most of the colors of the rainbow.
contains the rainbow and microwaves
contains all the colors of the rainbow AND ultraviolet light.
