Quiz on Light Waves and Reflection of Light

What type of wave is light classified as?

• Longitudinal waves
• Transverse electromagnetic waves
• Mechanical waves
• Sound waves

If the speed of light is constant in a medium, how does the wavelength relate to the frequency?

• Wavelength is directly proportional to frequency
• Wavelength is inversely proportional to frequency
• Wavelength equals frequency
• Wavelength is independent of frequency

What happens to the size of the image in a pinhole camera as the distance from the object increases?

• The image becomes larger and brighter
• The image becomes smaller and brighter
• The image remains the same size
• The image becomes blurred

In the experiment to observe reflection, what is the purpose of the normal line drawn at right angles to the mirror?

• To measure the speed of light
• To indicate the angle of incidence
• To show the position of the optical pins
• To determine the wavelength of light

What is the relationship between the angle of incidence and the angle of reflection?

• Angle of incidence is greater than angle of reflection
• Angle of incidence is less than angle of reflection
• Angle of incidence equals angle of reflection
• There is no relationship

What type of image is formed by a plane mirror?

• Real and inverted
• Virtual and erect
• Real and erect
• Virtual and inverted

Why does a wider pinhole in a pinhole camera result in a blurred image?

• It allows more light to enter
• It changes the wavelength of light
• It increases the angle of incidence
• It causes overlapping rays

What is the effect of light traveling in straight lines?

• It creates colors
• It produces shadows
• It bends around obstacles
• It increases brightness

How far behind the mirror is the image formed compared to the object in front of it?

• Closer than the object
• The same distance as the object
• Farther than the object
• It varies depending on the object

What is the significance of the optical pins in the reflection experiment?

• They measure the speed of light
• They help visualize the path of light rays
• They create the image
• They are used to calculate frequency
