Which of the following is true about an apple that appears red?

It reflects red light and absorbs all other colors

It absorbs red light and reflects all other colors

It transmits red light and reflects all other colors

It reflects back all the colors

Why is it you can hear around a corner, but you can not see around a corner?

Sound waves are able to diffract

Sound waves are able to refract

Light waves are able to diffract

Light waves are able to refract

When a pencil is placed in a glass of water, the pencil appears broken at the surface of the water. This is because:

Light wave slows down when it moves from air to water

Light wave speeds up when it moves from air to water

Light wave stops when it hits the water

There is no change in the light wave's speed

Which of the following lists the EM spectrum in correct order from LOWEST frequency to HIGHEST?

Radio Waves, Microwaves, Infrared, Visible Light, Ultraviolet, X-Rays, Gamma Rays

Gamma, Microwave, Infrared, Ultraviolet, Visible Light, X-Rays, Radio Waves

X-Rays, Infrared, Ultraviolet, Visible Light, Gamma Rays, Microwaves, Radio

Microwaves, X-Rays, Gamma Rays, Ultraviolet, Infrared, Radio Waves, Visible Light

Through which medium does a light wave travel the fastest?

Medium does not affect the speed of the wave

The reason that a police car's siren sounds higher in pitch as it approaches you, is because the truck pushes the sound waves together, so that the sound wavelengths in front of the truck gets shorter. This causes the

Frequency to increases, which increases the pitch

Velocity to decrease, which increases the frequency

Frequency to decreases, which decreases the pitch

Wavelengths to get longer, which increases the pitch
