💡 Hint

Common Mistakes

Using 'c' instead of 'speed_of_light' causes a NameError.

Confusing Planck constant names with speed of light.

The speed of light constant is named speed_of_light in scipy.constants.

medium

Complete the code to print the value of Planck's constant from scipy.constants.

SciPy

from scipy.constants import [1]
print(planck)

💡 Hint

Common Mistakes

Using 'hbar' instead of 'planck' imports the reduced Planck constant.

Using 'c' or 'speed_of_light' imports the wrong constant.

The Planck constant is named planck in scipy.constants.

hard

Fix the error in the code to correctly import and print the reduced Planck constant.

SciPy

from scipy.constants import [1]
print(hbar)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Importing 'planck' instead of 'hbar' causes a NameError.

Using 'speed_of_light' or 'c' imports unrelated constants.

The reduced Planck constant is named hbar in scipy.constants.

4fill in blank

hard

Fill both blanks to create a dictionary with keys 'c' and 'h' for speed of light and Planck constant values.

SciPy

from scipy.constants import speed_of_light, planck
constants = {'c': [1], 'h': [2]
print(constants)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'c' or 'h' as values instead of the imported constants.

Mixing up speed_of_light and planck in the dictionary.

Use the imported names speed_of_light and planck to assign values.

5fill in blank

hard

Fill all three blanks to create a dictionary with keys 'c', 'h', and 'hbar' for speed of light, Planck constant, and reduced Planck constant.

SciPy

from scipy.constants import speed_of_light, planck, hbar
constants = {'c': [1], 'h': [2], 'hbar': [3]
print(constants)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Swapping the values for 'c' and 'h'.

Using string keys as values instead of constants.

Assign the correct imported constants to each key in the dictionary.
