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 frequency?

• Wavelength is directly proportional to frequency
• Wavelength is inversely proportional to frequency
• Wavelength is independent of frequency
• Wavelength equals 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 for observing reflection, what is the purpose of the normal line?

• To measure the speed of light
• To indicate the angle of incidence
• To show the direction of the incident ray
• To represent the position of the mirror

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

Which of the following describes the image formed by a plane mirror?

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

What effect does widening the pinhole in a pinhole camera have on the image?

• The image becomes sharper
• The image becomes blurred
• The image becomes brighter
• The image size increases

When light rays are extended behind a mirror, what type of image is formed?

• Real image
• Virtual image
• Inverted image
• Erect image

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

• To measure the speed of light
• To mark the path of light rays
• To create shadows
• To adjust the angle of incidence

How does the wavelength of light compare to its frequency?

• Short wavelengths correspond to low frequencies
• Short wavelengths correspond to high frequencies
• Wavelength and frequency are unrelated
• Wavelength is always greater than frequency
